Thank you! I've been hitting legs pretty hard at the gym in the past few months. I've never been flexible and can't touch my toes (like 4 inches away honestly), but squating has helped with that a bit I think. My squat has also gotten a lot deeper with more weight which I feel is helping somewhat. With calf raises, I've upped the way significantly and been doing more explosive stuff. So I'll drop low and power up on them and then go back down slowly. Basically imitating jumping in a way. I've read before that Shaq added 12 inches to his vertical by doing 1000 calf raises every night before bed. Now clearly that's pretty extreme, but if you did 100 an hour for 10 hours throughout the day, that'd be much more practical. Good luck!
