Plyometrics seem like the best idea for what I am trying to achieve but this website is giving me a bit of confusion. I just want to clear things up a bit. What do you think about this website? https://www.athleticquickness.com The one book I am looking at is called "Jump Higher With Isometric Training" It involves using a resistance band. There is a 80% that this is just a money-making scheme, but there might be some truth to what they talk about. The reason plyometric are effective are because they train fast-twitch muscle fibers. You said that doing exercises that mimic the motion that you want to improve on is a good way to go. What if I used an isometric approach while still mimicing the jumping motion? Is that possible? Another question I have is that if strengthening the calf is important, I should do calf raises right? That wouldn't put enough stress on my calf muscle to recruit fast twitch muscle fibers unless I did it while holding a barbell. Should I do calf raises without weights but in high reps like 200-300 or should I do it with weights with sets of 3 and 7 reps? I heard a suggestion about putting your toes on the edge of a stair so your heels come off a little. Would that put additional pressure on my calves to grow?
