Picking up heavy things

Started back to strength training today.  Per my usual routine, I’m starting with the Body For Life strength training for the first three weeks, then launch into P90X, but only the strength training/core routines.  I find that after a long lay off from strength training, I need to rebuild some strength before moving into P90X and the BFL workouts are perfectly suited.  I can usually knock them out in about 45 minutes, hitting all the major muscle groups in each session.  I’m going to skip the P90X aerobic workouts since I’ll be getting plenty of aerobic work with the 1/2 marathon training.
