is there anything i can do about this other than icing my body? i usually do cardio for about an hour (running/walking intervals), and then move into different exercising depending. i do a lot of squats/lunges/leg extension type stuff, various stuff for my arms/chest, abs, back, everything. i work every muscle group in one night, which i know is probably a no no, considering muscles need a chance to rest, but i rest on the weekends.. i also have been adding resistance to my training in order to increase my muscle definition and what not, but i'm finding after 1-2 sets, my arms, legs, or whatever i am working feels like jello, and shakes uncontrollably, and then just immediately gets tired. tonight, on the way home, i felt like i couldn't even hold my arms on the steering wheel, or walk inside the house. what do you all think?
