Overtraining for long periods of time is bad. Short-term, planned overtraining, however, can be a massively powerful tool.
Functional overreaching is essentially short-term overtraining where you have a goal of digging yourself into a recovery ditch. You intentionally push your training past your body’s ability to recover before backing off, super-compensating, and jumping out of that recovery hole to new levels of strength and muscle. Doing so allows you to benefit from the harder training as your body gets a chance to recover.
We want to maintain a fairly constant back angle through the first pull, although we’ll nearly always see a slight change. It’s important to understand what actually constitutes the starting positionbecause this is a common source of confusion and argument when suggestion the back angle shouldn’t change considerably—the starting position is the posture you’re in the moment the bar begins to separate from the floor. It’s not whatever low-hipped, shoulders-behind-the-bar preparatory position or any given point of a dynamic startyou feel like picking.
The goal is to prevent an excessive and unwanted shift in position. This is a quick shift very quickly after the bar leaves the floor. You’ll recognize it as a sudden rising of the hips while the bar travels relatively little. The hips shooting up dramatically more than the shoulders and bar rise creates a two primary potential problems: It tends to shift balance too far forward, and it tends to force an early second pull, which reduces bar speed and elevation and also disrupts balance.
