I just started back up. I've done it twice before. Then in Dec I tried Insanity. Got bored with it after a month and quit. I don't need to lose weight and I really missed lifting weights. Then I took a couple weeks off of everything and started p90x again. I've lost a TON of strength, which is what I was afraid of by doing insanity.
I'm doing the hybrid version...p90x on the lifting days, Insanity on the cardio days. I just gotta figure out the best insanity routine to do in relation to the p90x days. ie not doing Cardio Power the day before Legs/Back.
I've finally made a hybrid version/schedule that works really well for me. Three days on, One day off. Repeat for 3-4 weeks, take a week off.Phase1
Day 1 - Chest & Back (following the bench press routine in the spreadsheet found
here) & Ab ripper X or Cardio Abs.
Day 2 - Shoulders & Arms & Ab ripper X or Cardio Abs.
Day 3 - Insanity Plyo Cardio or Pure Cardio or P90X Plyo
day off then repeat
The only thing I feel like I'm missing is the P90X Legs routine. Maybe replace a cardio plyo day with it?
