TL;DR

The four things you'd lose by not watching

4 items
1

Dr. Mike explains that a 500-rep bicep workout can be scientifically reasonable for experienced lifters, as research shows no upper limit to weekly set volume for hypertrophy, but warns of rhabdomyolysis risk for novices.

2

He notes that Smaev's 1000-rep arm workout relies heavily on warm-up sets and partial range of motion to manage fatigue, making it far less insane than the headline number suggests.

3

He recommends supersetting triceps isolation with push-ups to maximize triceps stimulus while sparing the chest, and advocates occasionally flipping biceps/triceps order to prevent imbalances.

4

He promotes the Versa Grips Hyper Belt and RP Hypertrophy App as tools for training, with affiliate savings available through his links.

Partial ROM for high-rep arm training

WhatWhen performing extremely high-rep arm workouts (e.g., 500+ reps), use a shortened range of motion on curls and extensions to reduce mechanical work and muscle damage.
WhenDuring dedicated high-volume shock workouts, not as a default for regular training.
DoseLimit ROM to roughly the mid-range, avoiding full stretch or full contraction if it doubles the distance. Apply to all exercises in the session.
For whomAdvanced lifters attempting Smaev-style high-volume arm days.
WhyHalving the ROM roughly halves the mechanical work per rep, allowing you to accumulate more total reps before reaching a damaging level of muscle breakdown.
CaveatsThis sacrifices some hypertrophy stimulus per rep; for normal training, full ROM is superior. Use only when volume is the priority and recovery is the bottleneck.

Dr. Mike explains that while full ROM is better for growth, the context of a 1000-rep workout changes the calculus. The goal shifts from maximizing stimulus per rep to surviving the session without hospitalization. He and Scott agree that if forced to do 1000 reps, partials are the only viable option. This isn't a general recommendation but a tactical concession for extreme volume. He also notes that Smaev's enormous arms already limit his ROM on some exercises (e.g., biceps physically block deeper elbow flexion), so his 'partials' are actually his full available range.

Mechanism

Mechanical work = force × distance. Reducing distance reduces total work and associated muscle damage (sarcomere disruption, calcium influx, inflammatory response), lowering the risk of rhabdomyolysis.

But in order to survive 500 reps, you probably don't want to double the range of motion of each rep because that doubles the mechanical work. It doubles roughly the damage that you get.

Also said
“So if you're going to do Scott, if you had a gun to your head and says you have to do a thousand rep arm workout, would you do it partial or full round? Partial. 100%.”— Reinforces the pragmatic necessity.

Rotate biceps/triceps order on arm day

WhatPeriodically switch which muscle you train first in your arm workout to prevent one from consistently getting more energy and attention.
WhenEvery few weeks or training cycles, or whenever you notice one muscle lagging.
DoseNo fixed frequency; flip the order for a mesocycle (4–6 weeks) or simply alternate every other arm day.
For whomAnyone who trains biceps and triceps in the same session.
WhyThe muscle trained first gets the freshest neural drive and energy; always prioritizing one can lead to asymmetrical growth.
CaveatsIf a biceps pump severely limits your triceps ROM, you may prefer to keep triceps first most of the time and only occasionally flip. Listen to your body.

Dr. Mike shares that he personally prefers triceps first because a biceps pump restricts his elbow flexion, making triceps exercises feel awkward. However, he recognizes that this habit could shortchange biceps growth over time. His solution is to occasionally flip the order, ensuring both muscles get periods of prioritized training. This is a simple programming tweak that costs nothing and can help balance development.

Personal experience

I like to train my triceps first and then my biceps because if I train my biceps first, the pump is big enough to limit my range of motion on triceps and the exercises don't feel as great.

Every now and again, flipping the script is a really good idea if you're going to do an arm day.

Triceps-first superset with push-ups

WhatPerform triceps isolation exercises (e.g., cable pushdowns) before compound pushing movements like push-ups to pre-fatigue the triceps and make them the limiting factor.
WhenOn arm days or upper-body days when you want to emphasize triceps without overly taxing the chest.
DoseDo 2–4 hard sets of isolation, then immediately follow with push-ups to failure or near-failure. Can be done as a superset or giant set.
For whomLifters who want to prioritize arm growth without adding a separate chest day, or who find their chest takes over in pressing.
WhyTriceps are fresh for isolation work, then become the weak link in the compound movement, ensuring they receive maximal stimulus while the chest gets a lighter stimulus, preserving it for other training days.
CaveatsIf done in reverse (push-ups first), the chest may fatigue and limit triceps isolation performance. Ensure proper push-up form with elbows close to the body to keep emphasis on triceps.

Dr. Mike praises Smaev's order: triceps cable work first, then push-ups. He explains that this sequence 'nukes the shit out of your triceps' while saving the chest for another day. He contrasts it with the reverse order, where chest fatigue would limit triceps isolation. He even suggests a triple superset: cable extensions → Smith machine French press → close-grip push-ups, dropping to the floor immediately after the French press. This is a time-efficient way to accumulate high triceps volume with minimal rest.

Mechanism

Pre-fatiguing a synergist muscle (triceps) in a compound movement (push-up) forces it to work closer to its maximal capacity, increasing motor unit recruitment and metabolic stress in that muscle while the primary mover (chest) operates below its maximal voluntary activation due to the reduced load tolerance of the fatigued synergist.

Supering smart. You do your triceps first, your push-ups are going to be limited by your triceps, and then you do your triceps again when you do push-ups. Real smart.

Also said
“If it's the other way around, triceps can be limited by chest and then your triceps are tired for push-ups later. But if it's this way, it can be a really awesome way to save your chest for another day of training and nuke the shit out of your triceps.”— Explains the strategic benefit of the order.

Triple superset for triceps

WhatPerform cable triceps extensions, immediately followed by Smith machine French presses, then drop into close-grip push-ups with elbows by your sides, all with minimal rest.
WhenAt the end of an arm workout when you want to maximize triceps volume in a short time.
DoseSeveral rounds (e.g., 3–5 rounds) of 20–30 reps per exercise, totaling around 500 reps for triceps.
For whomAdvanced lifters looking for a high-volume finisher.
WhyCombines different resistance profiles (cable constant tension, Smith machine loaded stretch, bodyweight metabolic stress) to fully exhaust the triceps from multiple angles.
CaveatsRequires access to a cable station, Smith machine, and floor space. High fatigue; not suitable for beginners. Ensure proper warm-up and use partial ROM if needed to manage volume.

Dr. Mike describes Smaev's approach: after cable extensions, he walks to the Smith machine for French presses, then immediately drops to the floor for push-ups. He endorses this as an excellent way to accumulate high volume efficiently. He notes that Smaev aims for 20–30 reps per exercise and totals around 500 reps for triceps. This protocol is essentially a condensed version of Smaev's method, adapted for those who want to try a high-volume arm finisher.

Mechanism

The sequence moves from isolated constant tension (cable) to loaded stretch under stability (Smith machine) to closed-chain metabolic stress (push-ups), targeting different portions of the force-velocity curve and fatiguing both fast-twitch and slow-twitch fibers through varied loading.

If you want to do that triple superset after, just drop to the ground as soon as you're done. So, you do cable extensions, walk over, do the French press on the Smith machine, and then as soon as you're done with that, drop into regular close grip push-ups with your elbows by your sides.

Pyramid warm-up for high-volume arm training

WhatStart with light weights and gradually add weight each set while keeping reps constant (e.g., 20 reps), stopping each set well short of failure until the final heavy sets.
WhenAt the beginning of a high-volume arm workout to accumulate reps without excessive fatigue.
DosePerform 4–6 warm-up sets, increasing weight each set, before reaching your top working weight. The early sets should feel easy.
For whomAnyone attempting high-rep arm workouts who wants to manage fatigue.
WhyAllows you to log many reps (contributing to a high total) without causing significant muscle damage, preserving recovery capacity for the harder sets later.
CaveatsDon't count these as hard sets; they are preparatory. If time efficiency is a priority, limit warm-ups and get to hard sets sooner.

Dr. Mike observes that Smaev pyramids up in weight, keeping reps around 20 and stopping each set before failure. This explains how the total rep count reaches 500 without destroying recovery. He contrasts this with a more time-efficient approach of doing fewer warm-ups and more hard sets, but acknowledges that if the goal is to luxuriate in the pump and spend time in the gym, this method works. The protocol is essentially: if you want to try a 500-rep workout, use a long pyramid to inflate the rep count safely.

Mechanism

Submaximal loads recruit fewer high-threshold motor units and cause less metabolic stress and mechanical tension, resulting in minimal muscle protein breakdown and allowing repeated bouts without accumulating damage.

When you see a workout on paper that's 500 reps for biceps, you're like, 'How can anyone recover from that?' You see it in real life, it's a lot of warm-up sets.

Also said
“The number of ultra hard sets, probably substantially smaller than the total. And the number of repetitions that get close to failure is substantially lower than what you would expect with 500 reps if each one of the sets to compose those reps was a real hard working set.”— Quantifies the discrepancy between perceived and actual hard volume.

the '500 reps' claim is misleading because many are warm-up sets

during the biceps exercise breakdown

Smaev's 500 biceps reps include numerous submaximal pyramid sets that never approach failure, so the effective hard-set volume is much lower than the rep count suggests.

Why this matters: Demystifies how someone can recover from '500 reps'—it's not 500 reps of hard training, but a mix of warm-ups and a few hard sets.

Background

When people hear '500 reps for biceps,' they imagine 30–50 all-out sets to failure, which seems impossible to recover from. In practice, pyramid-style loading means early sets are light and stopped well short of failure.

Dr. Mike observes Smaev's training footage and notes that he pyramids up in weight while keeping reps around 20, stopping each set before reaching failure. This means the first several sets are essentially warm-ups, contributing to the rep count but not to deep muscle damage. The number of truly hard, failure-approaching sets is substantially smaller. This explains why Smaev can handle such volume without breakdown—it's not as stimulative per rep as it appears. Dr. Mike even jokes that he was about to 'eat his words' expecting failure on every set, but then sees Smaev stop comfortably short. The takeaway: don't equate total reps with hard training volume; the effective dose is much lower.

When you see a workout on paper that's 500 reps for biceps, you're like, 'How can anyone recover from that?' You see it in real life, it's a lot of warm-up sets. The number of ultra hard sets, probably substantially smaller than the total.

Also said
“I'm about to eat my words here in a bit. Watch him go to failure on all these. Okay, he just stopped. Makes sense. ... that's nowhere near failure, which is kind of a good thing because then he's for sure not going to have any recovery problems from that many reps.”— Confirms the observation that the sets are submaximal.

alternating biceps/triceps order prevents imbalances

during discussion of exercise order

Always training one muscle first can cause the other to lag; periodically flipping the order ensures both get equal attention and energy.

Why this matters: A simple, actionable tweak that many lifters overlook, based on the speaker's personal experience with pump interference.

Background

Many lifters have a fixed arm-day order (e.g., always triceps first). Dr. Mike notes that a biceps pump can physically limit triceps range of motion if done first, but always doing triceps first can shortchange biceps growth.

Dr. Mike shares his personal preference: he trains triceps first because a biceps pump restricts his elbow flexion on triceps exercises, making them feel awkward. However, he acknowledges that consistently prioritizing triceps can leave biceps under-stimulated since energy and focus are highest early in the workout. His solution is to occasionally flip the order—maybe every few weeks or months—so that each muscle gets a turn at full freshness. This is a low-cost way to ensure balanced development without overhauling your entire program.

Personal experience

I like to train my triceps first and then my biceps because if I train my biceps first, the pump is big enough to limit my range of motion on triceps and the exercises don't feel as great.

However, always training triceps first and biceps after can make it so that your most of your energy goes into triceps and then your biceps get the short end of the stick and they don't grow as well. So, every now and again, flipping the script is a really good idea if you're going to do an arm day.
