Warm‑up for sternum pull‑ups
Mike calls sternum pull‑ups a ‘very hardcore exercise’ and insists on a specific warm‑up. The shrug‑ups (which he describes as ‘a third of a pull‑up’) activate the lats, biceps, rear delts and lubricate the shoulder and elbow joints. After a brief rest you progress to half pull‑ups, moving only through the middle portion of the range. Finally, you perform full chin‑height pull‑ups to prime the full movement pattern. This sequenced ramp ensures the working set of sternum pull‑ups can be taken to failure safely.
Graduated loading increases synovial fluid in the joints, raises muscle temperature, and enhances neural drive, reducing the likelihood of strains in the deep stretched position of the sternum pull‑up.
Mike uses this warm‑up personally and with clients before any maximal pull‑up effort; he states it’s essential to ‘not just get into these sorts of situations.’
Do not just get into these sorts of situations. It's a very hardcore exercise. So, at first, you're going to ... do some kind of shrug-ups, where it's like a third of a pull-up. Really warms up the lats, warms up the back, warms up the biceps and the rear delts, and especially your shoulder and elbow joints.
