I am a girls h.s. track coach and we don't have access to a weight room so my idea this year was to do a body weight/general strength curcuit. We have body bars, resistant bands and I have a good idea of what excercises I want to do but I question the length of time and reps they should do. 30 secs on 30 off x2? Any suggestions? Another question…before or after a workout(easy days)?
Thanks!
