Today for an extra warm up for the legs I put in Lower Body Blast and did the warm up, cardios, and sit and slide, 15 minutes, 97 calories. I then did STS disc 17 legs, 48 minutes, 337 calories. I did not up the weight too much this time. I am only 4 weeks back to lower weight training after the knee surgery. Max weights for the dumbbells was 31.5. I will get my strength all back. I just don't want another injury. I followed withP90X Ab Ripper X2, 16 minutes, 68 calories and finished with the c/d Neuro Integrated stretch from P90X 2 PAP lower body, 11 min., 24 cal.. I really like the stretching done in P90X2 and this one is all lower body. Total time was 90 minutes and calories burned 526. I wish the Beachbody workouts had chapter lists like Cathe does though. I can get them from the P90X app thought.
