What are your conditioning goals?
really there five characteristics that enhance the development of the tennis player one is speed two is agility, three flexibility for aerobic endurance, five muscular strength now you really wouldn’t go about and measure yourself in those categories, but here’s how you know that you’re not in shape; if you keep losing matches in the third set and in the first two sets you were very close 7-6,7-5,6-4 but, the third set is 6-1, 6-0,6-3 then you know that fatigue is having its way with you in the third set. This result tells you that your conditioning plan is not working. Please see the signs off fatigue.
