In anticipation of summer and not being able to get to the gym because of the kids being out of school I just ordered the 3 strength series videos and 2 step videos (I also teach Spinning and hopefully will be passing my ACE exam to teach aerobics myself in May). I was wondering, does CAthe recommend doing each of the strength tapes once a week or more often? I'm assuming thats the case but wanted to verify that. Also, is it recommended/okay to do a strength tape and then do a cardio i.e. step tape and/or class? My plan was to do a strength tape M-W-F followed by some sort of cardio and on T-TH-S just cardio.
