TweetI do it quite often with legs. Ive even done chest in AM and back in the PM before. If you have the energy and the ability to recover I dont see a prob. Plus you need time to rest as well which usually wont be the case if you are working full time or married etc. Certain workouts i think are easier to do this with than others. Sometimes i will just lift heavy with few reps and sets, this is easy for me to recover from as opposed to tons of volume.
