Sticking Point

The sticking point exists for precise biomechanical reasons. In every exercise, leverage changes throughout the range of motion. There are angles where the muscle has a mechanical advantage and angles where it's at a disadvantage. The sticking point corresponds to the zone where the combination of muscle length, force moment, and lever arm is least favorable. In the squat, it's usually just above parallel. In the bench press, a few centimeters above the chest. In the deadlift, around the knees.

Identifying your sticking point is the first step to overcoming it. Film your heavy sets and watch where the bar slows down. That point tells you exactly where you're weak. The strategies for improving it are varied: isometrics at the critical angle, partial-range exercises that work specifically in that zone of the ROM, accessory exercises that strengthen the muscles that are weakest in that segment, and the use of chains or bands that progressively increase resistance through the movement.

A common mistake is confusing the sticking point with general fatigue. The sticking point is angle-specific: it always shows up in the same zone of the ROM, regardless of which rep you're on. If the bar slows down at different points depending on the set, you probably don't have a true sticking point but simply a load too close to your max or a fatigue level that's too high. The difference matters, because the solutions are different.
