Ever push through an exercise that burns so much it must be working, only to wonder later if you were actually doing anything useful?
Feelings can be deceiving!
Just because a movement feels hard or creates a burning sensation doesn't necessarily mean it's effective.
Here's a great example using the hamstrings: This muscle's job is to extend the hip and bend the knee.
In an exercise like the "ball squeeze," in the reel, the hip is extended and the knee is bent, which actually puts the hamstring in an overly shortened position.
When a muscle is that shortened, it can't produce much force.
There's simply too much slack in the system.
Compare that to the "ball curl," where the hip is flexed and the knee is straightening.
This puts more length into the hamstring, positioning it to actually produce force.
Same muscle, same general movement pattern, completely different result, all because of position.
Position plays a huge role in whether an exercise is truly loading the muscle you're trying to target.
Have you ever caught yourself doing an exercise that felt intense but turned out to be missing the mark?
