TL;DR

The four things you'd lose by not watching

4 items
1

Mike Israetel tried a 20-minute EMS (electrical muscle stimulation) workout that claims to replace 2 hours of gym training; he found it intense but not a full replacement for a heavy lifting session.

2

He sees value in EMS for improving mind-muscle connection, especially for hard-to-feel muscles like biceps or rear delts, and for injury rehabilitation.

3

Mike emphasizes that EMS is not a magic bullet: you must control your diet and bring maximum effort, choosing challenging weights and squeezing hard through full range of motion.

4

He suggests combining EMS with heavy weightlifting could be highly effective, and recommends using the RP Hypertrophy app to program EMS-enhanced workouts.

EMS Full-Body Workout Session (as experienced)

WhatA 20-minute session wearing a full-body EMS suit with electrodes on all major muscle groups, performing exercises like squats, deadlifts, and cat pose while the machine delivers electrical impulses to contract muscles.
WhenNot specified; can be done as a standalone workout.
Dose20 minutes, with the machine cycling through muscle groups and then all at once.
For whomPeople looking for time-efficient training, but Mike suggests it's best for those who already train hard.
WhyTo provide a full-body muscle stimulation in a short time, claiming to replace longer gym sessions.
CaveatsMike notes it's not a replacement for a good diet or heavy training; you must bring effort.

The session began with a warm-up on an AI bike (2x20-second sprints). Then the trainer wetted the EMS suit for conductivity and placed it on Mike. The machine activated muscle groups sequentially (legs, glutes, upper back, middle back, biceps, chest, abs) while Mike performed movements like squats, arm holds, and cat pose. The intensity was high, causing involuntary contractions and a bicep cramp. The session ended with a muscle relaxation/massage setting to clear lactic acid. Mike found it intense and effective for feeling muscles.

Personal experience

Mike's experience: he found it intense, got a bicep cramp, and felt his glutes strongly. He later had post-session twitching.

All your muscles will go working at the same time. That's the biggest challenge.

Also said
“I'm going to turn each muscle group separate like one at a time and then all your muscles will be working at the same time.”— Trainer explains the protocol.
“This suit has electrodes on all your major muscle groups. So now I wet the suit to provide the conductivity.”— Setup details.
“That hurts. Oh, that was intense. Oh, bicep cramp.”— Mike's real-time reaction showing intensity.

Use EMS to Improve Mind-Muscle Connection on Lagging Muscles

WhatApply EMS to a specific muscle you struggle to feel (e.g., biceps, rear delts) while contracting it, then take that heightened awareness into your regular gym training.
WhenDuring dedicated EMS sessions or as a pre-workout primer.
DoseNot specified; likely a few minutes per muscle.
For whomLifters who have difficulty activating certain muscles.
WhyEMS forces muscle contraction, making you acutely aware of the sensation, which can be transferred to voluntary contractions.
CaveatsMust be combined with hard effort in the gym; EMS alone won't build the muscle without progressive overload.

Mike explains that many people can't feel their biceps or rear delts during exercises. By using a direct EMS unit on those muscles, you can learn what it feels like when they contract. Then, when you go to the gym and perform curls or rows, you can replicate that sensation, improving mind-muscle connection and potentially hypertrophy. He suggests using the RP Hypertrophy app to program your training and even label exercises as 'plus EMS' if you continue using the device during workouts.

Personal experience

I have trouble really kind of recruiting my biceps, I think, or rear delts, stapling those electrodes to that and then using the app might be a real good idea.

If you're having trouble feeling a specific muscle and on top of that you're working really hard, then yeah, this system can offer an advantage.

Also said
“You put the EMS situation on, you contract those muscles. You're really going to get a mind muscle connection.”— Direct instruction.
“What you're going to do is you're going to take that mind muscle connection that you learned with EMS. You're going to take it to the gym.”— Transfer step.

Combine EMS with Heavy Weightlifting

WhatWear an EMS suit while performing heavy compound lifts (squats, deadlifts, etc.) to add electrical stimulation on top of mechanical tension.
WhenDuring regular gym sessions, with a practitioner to control the device.
DoseNot specified; presumably during working sets.
For whomAdvanced lifters seeking new stimulus; requires access to EMS suit and knowledgeable operator.
WhyThe EMS could increase muscle activation and metabolic stress beyond what weights alone provide, potentially enhancing hypertrophy.
CaveatsMike hasn't tried this; it's speculative. Safety and practicality need to be evaluated.

Mike hypothesizes that taking the EMS suit into a gym and using it during heavy lifts could be very effective. He imagines doing each rep with EMS firing, which might recruit more motor units and create a unique training stress. He doesn't provide details on programming, but suggests it's worth exploring. This idea stems from his observation that EMS alone is intense but not a full workout; combining it with heavy loads might yield the best of both worlds.

What I would be really, really, really curious about is taking that bodysuit and a good practitioner into a real gym, having to lift big weights and have EMS on top during each repetition. I think that might work out pretty goddamn well.

Use EMS for Injury Rehabilitation

WhatApply electrical muscle stimulation around an injured area to contract muscles without loading the injured tissue, aiding recovery and preventing atrophy.
WhenDuring rehab, as directed by a physical therapist.
DoseNot specified; depends on injury.
For whomIndividuals recovering from musculoskeletal injuries.
WhyEMS can activate muscles without joint movement or heavy load, reducing risk of re-injury while maintaining muscle function.
CaveatsShould be done under professional guidance; not a substitute for proper rehab exercises.

Mike emphasizes that this is the number one application of EMS. He explains that if you have an injury, using EMS around that area can help contract the muscles safely, which is beneficial for coming back from injury management. He doesn't go into detail on protocols but strongly endorses it.

The number one application of this is injury rehab. If you have some kind of injuries, using electrical muscle stimulation around that area can help contract those muscles without putting you at risk coming back from injury management situation.

Maximize EMS Workout Effectiveness with Effort and Weight Selection

WhatWhen doing an EMS session, choose challenging weights (not light), squeeze muscles hard, and move through a full range of motion.
WhenDuring any EMS workout.
DoseThroughout the session.
For whomAnyone using EMS for fitness.
WhyEMS provides additional stimulation, but voluntary effort amplifies the training effect; going light and passive yields minimal gains.
CaveatsDon't sacrifice form; ensure the EMS intensity is tolerable.

Mike admits he chose little weights because he was a 'wuss' and regrets it. He advises viewers to choose big weights, squeeze the crap out of their muscles, and use full range of motion. He stresses that EMS is the icing on the cake, not a replacement for hard work. If you just let the machine do the work, you'll get very few gains. This advice is crucial for anyone considering EMS training.

Personal experience

I chose little weights because I'm a wuss. I should have chosen the big weights.

Choose the big weights. Really squeeze the crap out of your muscles. Go through a full range of motion when you're doing this.

Also said
“You will get way more out of this if you show up ready to work.”— Emphasizes effort.
“This is something that is the icing on the cake for a good workout. It does not replace a good workout.”— Sets expectations.

Control Diet When Using EMS

WhatDo not rely on EMS to burn significant calories; maintain a calorie-controlled diet to see body composition results.
WhenAlways, alongside EMS training.
DoseN/A.
For whomAnyone using EMS with body composition goals.
WhyEMS does not magically burn off calories; its calorie burn is modest, so diet remains key for fat loss or weight management.

Mike warns that EMS doesn't replace a good diet. He says the calorie burn is not 'psychotic,' so if you're lazy about diet, EMS won't compensate. This is a common pitfall with any 'quick fix' modality.

You have to make sure to control your diet because this doesn't magically burn off calories because you're too lazy to go and work out by yourself.

Also said
“Yes, this will have a calorie burn, but it's not psychotic.”— Quantifies the burn as modest.

AI Bike Warm-Up (Tiger Mode)

WhatA 2x20-second sprint interval on an AI-guided bike that narrates a tiger chase scenario to motivate effort.
WhenAs a warm-up before EMS or any workout.
Dose2 rounds of 20-second all-out sprints.
For whomAnyone, but especially those who need a fun, engaging warm-up.
WhyTo elevate heart rate and prepare muscles for intense work.
CaveatsMike found it hilarious and intense; may not be suitable for those who dislike high-intensity cardio.

The bike has a 'tiger mode' where it tells you to pedal faster to escape a tiger, then relax when the tiger turns back. Mike did it without sneakers, which was awkward. He and his partner joked about it. It's a novel warm-up tool.

Personal experience

Mike did it and found it funny and challenging.

This is a AI curl bike. In 8 minutes you will experience a great warm up and great training.

EMS does not replace a full gym workout

near the end, after the workout

Mike concludes that 20 minutes of EMS cannot match the total muscular stimulus and calorie burn of a 2-hour intense weight training session.

Why this matters: He directly challenges the marketing claim of the EMS gym, providing a nuanced take based on his personal experience.

Background

EMS gyms often advertise that a short session equals hours of traditional training.

Mike and his training partner Jared had just completed a 2-hour push workout before the EMS session. He compares the intensity and stimulus, noting that while the EMS was intense and caused involuntary contractions, it didn't produce the same overall muscular work or calorie expenditure. He acknowledges that EMS has upsides but the claim of replacing 2 hours is 'a pretty big claim' and he doesn't think it holds up. He leaves open the possibility that combining EMS with heavy weights could bridge the gap.

Personal experience

Jared and I trained 2 hours before this push workout. That was pretty intense. Calorie-wise, total muscular stimulus wise, I don't think 20 minutes makes up for that.

I don't think 20 minutes makes up for that.

Also said
“I think EMS has its upsides. I think that's a pretty big claim.”— He acknowledges the claim is bold but doesn't fully endorse it.
“Was it 2 hours of workout worth of intensity? I don't know, man.”— He expresses uncertainty, not a definitive no.

EMS enhances mind-muscle connection for lagging muscles

after the workout, during his analysis

Mike found that EMS forced him to feel muscles he normally struggles to activate, and he suggests using it to learn that connection and then transfer it to regular training.

Why this matters: This is a practical, actionable insight that reframes EMS as a teaching tool rather than a workout replacement.

Background

Many lifters have difficulty feeling certain muscles (e.g., biceps, rear delts) during exercises, limiting hypertrophy.

Mike describes how the EMS suit made him acutely aware of his glutes and other muscles. He says if you have trouble feeling a muscle, EMS can help you establish a mind-muscle connection. He then recommends taking that learned connection to the gym and using the RP Hypertrophy app to program your training, possibly labeling exercises as 'plus EMS' if you continue using the device. He even suggests using a home EMS unit on specific muscles like biceps or rear delts to improve recruitment.

Personal experience

When that machine was on, uh, then uh, no, it's okay. I'm here in for a penny, in for a pound. Uh um it's um the machine is uh definitely helping me feel my glutes. and I have trouble really kind of recruiting my biceps, I think, or rear delts, stapling those electrodes to that and then using the app might be a real good idea.

If you're having trouble feeling a specific muscle and on top of that you're working really hard, then yeah, this system can offer an advantage.

Also said
“You put the EMS situation on, you contract those muscles. You're really going to get a mind muscle connection.”— Direct statement of the benefit.
“What you're going to do is you're going to take that mind muscle connection that you learned with EMS. You're going to take it to the gym and you are going to use the RP hypertrophy app to program your training.”— He outlines a specific protocol for transferring the skill.

Combining EMS with heavy lifting could be highly effective

after the workout

Mike hypothesizes that wearing the EMS suit while lifting heavy weights in a real gym could amplify the training stimulus significantly.

Why this matters: This is a novel, speculative idea from an expert that could influence future training methods.

Background

EMS is typically used in isolation with light movements; combining it with heavy compound lifts is not common.

Mike expresses curiosity about taking the bodysuit and a practitioner into a gym and doing heavy lifts with EMS activated during each rep. He thinks this might work 'pretty goddamn well' because the EMS would add extra muscle activation on top of the heavy load, potentially increasing motor unit recruitment and metabolic stress. He doesn't claim to have tried it, but his reasoning suggests it could be a powerful hypertrophy tool.

What I would be really, really, really curious about is taking that bodysuit and a good practitioner into a real gym, having to lift big weights and have EMS on top during each repetition. I think that might work out pretty goddamn well.

EMS is primarily for injury rehabilitation

during his final advice

Mike states that the number one application of EMS is injury rehab, as it can contract muscles around an injury without putting the area at risk.

Why this matters: He prioritizes a medical use over fitness, which may surprise those who see EMS as a workout shortcut.

Background

EMS has long been used in physical therapy.

Mike says that if you have an injury, using electrical muscle stimulation around that area can help maintain muscle activation and prevent atrophy while avoiding movements that could aggravate the injury. He calls it a 'real swell idea' and probably the top reason to use this modality. This aligns with clinical practice but contrasts with the gym's marketing.

The number one application of this is injury rehab. If you have some kind of injuries, using electrical muscle stimulation around that area can help contract those muscles without putting you at risk coming back from injury management situation.

EMS Training at the Miami Gym (unnamed)

Service

Mike visited a high-end EMS gym in Miami that offers 20-minute full-body EMS sessions with a trainer.

The gym provides the EMS suit, AI bike warm-up, and guided session. Mike found the trainer's instruction excellent and the experience intense. He doesn't explicitly recommend the specific gym, but his positive experience and the fact that he suggests trying EMS 'every now and again' implies endorsement of such services. He notes it's 'definitely something to try.'

vs alternatives

Compared to traditional gym workouts, it's shorter and more novel, but not a replacement.

Personal experience

He did the session and described it in detail.

This is definitely something to try every now and again, especially if you have trouble feeling specific muscles.

Also said
“Um you know what I think I like the best is uh your immersive presence and attention uh and an excellent instruction case.”— Praises the trainer.

Direct EMS Devices for Home Use (e.g., for specific muscles)

Tool

Mike mentions that if you have a 'newbie system at home' or access to direct EMS units that target one muscle, you can use them to improve mind-muscle connection on lagging muscles.

He doesn't name a brand, but suggests that such devices exist and can be paired with the RP Hypertrophy app. This is a recommendation for a category of tools, not a specific product. He implies they are useful for people who struggle to feel certain muscles.

vs alternatives

Compared to full-body EMS suits, these are more targeted and affordable.

Personal experience

He mentions he has trouble recruiting biceps and rear delts, implying he might use such a device.

If you have like a newbie system at home or something like that, access to one of those direct EMS systems that do this one specific muscle... stapling those electrodes to that and then using the app might be a real good idea.

AI Curl Bike (Tiger Mode)

Tool

The gym had an AI bike that guides you through sprint intervals with a tiger chase narrative. Mike used it as a warm-up.

The bike provides an 8-minute warm-up with 2x20-second sprints. It talks to you, telling you to pedal faster to escape a tiger, then relax. Mike found it entertaining and effective for getting his heart rate up. He doesn't explicitly recommend buying one, but it's a notable tool featured in the video.

vs alternatives

Compared to a standard stationary bike, it adds gamification and motivation.

Personal experience

Mike tried it and joked about it.

This is a AI curl bike. In 8 minutes you will experience a great warm up and great training.

RP Hypertrophy App

Product Sponsored · disclosed

Mike recommends using the app to program your training, whether with EMS or not, and suggests labeling exercises as 'plus EMS' if you combine them.

DisclosureDr. Mike is a co-founder of RP Strength, which makes the RP Hypertrophy app.

The RP Hypertrophy app is a training program app that auto-regulates volume and intensity based on your recovery and performance. Mike integrates it into his EMS advice: after learning mind-muscle connection with EMS, you take that to the gym and use the app to guide your workouts. He even suggests that if you use a home EMS unit on specific muscles, you can use the app to program those sessions. This is a clear product placement, but it's relevant to the topic.

Personal experience

Mike uses the app himself and developed it.

You are going to use the RP hypertrophy app to program your training, which you could technically do with EMS and label each exercise as plus EMS.

Also said
“And real talk, if you have like a newbie system at home or something like that, access to one of those direct EMS systems that do this one specific muscle, if you're really having trouble contracting a specific muscle, like I have trouble really kind of recruiting my biceps, I think, or rear delts, stapling those electrodes to that and then using the app might be a real good idea.”— Shows integration of app with EMS.
