The next camp is about 4 weeks away. I just wondered if in 4 weeks it is possible to see a difference. That is of course without over training.
Is he only doing aerobic running? It is ok for him to do some of that but he also needs anaerobic fitness -- wind sprints / interval training.
For his core strength he might perform a bit of medicine ball work -- but not too much. At his age it is probably not wise to engage in too much plyometric training. Jumping rope
is another good idea -- it is considered a low-level plyomentric exercise. It should help somewhat with his footwork/agility and hit overall fitness. He can incorporate skipping rope with his interval training. Jump (high intensity) for 20-30 seconds and then walk (low intensity) for 30-40 seconds. Rinse and repeat for 10 minutes or more.
