After establishing a strong foundation, adding variations to your movements is a fun way to mix up your workouts. Here I can be seen playing with different variations of Endo press to handstand sequences. Obviously, in order to work on these variations, a fundamentally sound handstand, press handstand, etc is required. Just like having a strong foundation is required to build a structurally sound house, having solid basics is a must to try harder variations of skills. Try doing it on movements you feel you have mastery of!
