First you must eat breakfast and eat meals every 3 to 4 hours. Cut out all sugar except for your pwo shake. I like to lift heavy but I limit my workouts to 30 minutes. I split my workouts into body parts. Its tempting to do too much but limit your time to 30 minutes and that includes a 10 minute warmup. I know I can't do a good leg workout in 30 minutes so I split legs into 2 days. This is what I am trying atm. Since my cancer (5 years ago) I don't heal so quick and I get tired easily.Its frustrating and I want to do much more but I feel the need to be practical and I am still enjoying the rewards. I've just got to be clever about it. Eat a meal before you workout things will be better.
