I am curious, in training to increase my explosiveness (sprinting, vertical jumping, etc.) would it be regressive to incorporate gymnast bodyweight exercises such as planche holds, and front lever holds, as well as things like RX squats (static leg holds in different positions), seeing that these types of exercises are meant more for absolute strength and muscular endurance. While I'm not able to do a full planche or front lever yet, I am getting very close, but I'm still not sure whether or not these exercises are helping or hurting my goal of increasing my sprinting and jumping ability. In addition, are there any diet tips out there for getting big, but at the same time remainng limber and quick. Thanks.
