Mucle milk light chocolate mint flavor!
I have yet to find a better tasting drink with as good a nutritional profile. I don't have it in front of me, but I think the pre-mixed drink boxes are 150 calories for 20g of protein with 4g carbs.
Plus mint is a stronger flavor and hides whey protein taste fairly well.
I drink one 1/2 an hour before I work out, every week day.
As for toning, I'd suggest 15 mins jogging on the elliptical as a warm up, then a toning based work out on the bowflex with girl reps (toning reps) of 3 sets of 15 at a lower weight. Do arms and one day, legs the next, and then back and core the next. One day off, and then do it again.
