Hello everyone I've been playing for quite a while now, and i always feel...rather weak, my smashes usually get the job done (but it's usually against people who can barely play), when i play with people who are significantly stronger, my smash is rather...pathetic compared to there's. Also, it is not just my smashing power, but i also try to aim for the power in my legs, i'm not the strongest singles player around so.... Here is what i have been told and currently doing... For about 2-3 months, I have been doing around 200-300 push ups a day, around 80-100 bench dips, and 50 starjumps, and 30 by 30 (30 seconds work, 30 seconds rest) of chinese foot work and around 15-30 minutes of skipping rope a day. Oh and the wrist curls with the dumb bells. Just tell me, should i be doing more? Are any of these exercises rather useless and i'm wasting my time? Etc.... P.S, i'm currently 15 and I can do around 50-90 push ups without stopping, is that good, average or rather bad?
