What are your favorite ideas/methods/training to aid with explosive power? I typically have the boxers I work with do 20 mins or so of abs and exercises at the end of our training session. I coach 4 sessions a week, but my more experienced ones typically come 3 days a week. Since my boxers are juniors, I try to keep the sessions to no more than an hour and a half.

These are the exercises I normally include:
1. Medicine ball throws. Single arm in Boxing stance and also twisting throws
2. Squat jumps and box jumps
3. Kettlebell swings and kettlebell squats.

3 sets each of varing reps.

And with abs, I prefer Russian twists (done properly), walking planks, exercises with feet evelated on a bit ball.
