Is it a good idea to take whey protein isolate as a recovery drink after I do the insanity fitness program? And before bedtime?
Maybe, but.. Insanity is a vigorous exercise program that engages all major & core muscle groups, stimulates the release of glycogen stores and the rapid and efficient uptake of oxygen to fuel activity. Recovery from the demands of such a program requires some protein and also a high GI food to promote growth and replenish glycogen. Adding some fruit or dextrose will do the trick!
