I was doing both cardio (WATP, YBB, TJ) and strenght two days a week using free weights and resistance bands, but i noticed all of my videos have strength built in with cardio. Most all of them. Do you think it's ok for me to just use the videos or shoudl I really incorporate additional strength? Strength is boring to me. But I look fwd to videos, and doing the resistance bands or weights with cardio. What do you think? what do you do yourself?

I do not do any sort of strength training with cardio videos. I don't "mix and match". I do them separately and I really push myself with strength training.

Well if you feel like you're getting a good enough strength workout in the videos, why not keep it? I personally enjoy mixing the two up, it seems less boring. My 'strength' workouts are an hour long kickboxing class or the 30 day shred dvd. Both of them are cardio+strength.
Just make sure you keep challenging yourself by increasing the resistance when it gets easy.

i have 3 days of just strength. If im feeling especially perky aftwerwards, i'll do another strength or a TJ. Also do interval training once a week though - cardio then weights, then cardio again, thn weights again (as one work out)
