Hello,
I' m tennis coach in Greece and I want to ask anyone how many sit-ups must
do a 12 year old, a 14 year old and a 16 year old male or female competitive
player in every training session?
I also want to ask how many hour these ages must work their aerobic
endurance in a session?
Best regards,
Dolianitis Manolis
