In order to continue to make changes to your body and avoid plateaus, you have to keep your body guessing. Too much predictability ultimately causes progress to come to a halt. In that way, the body is no different than relationships, day to day routines, and making the same food the same way over and over again - boring and stagnant.
This exercise set uses numerous training principles to shock the muscles into responding and changing:
Isolation through unilateral focus
Overload - You'll know exactly what I mean when you try the set
Partial Reps - A favourite add on of mine
Confusion - your muscles don't know what's coming or when it's going to end
If you don't have a bar like I do in the video, you can use a dumbbell, or even no weight at all, as the balance component itself is often challenging enough!
