Want to gain 5 lbs of leaner muscle tissue? Try making this change for 10 weeks to your program.
Consume a shake or drink that includes Whey and Casein proteins after each workout for the next 10 weeks.
Whey Protein digest quickly, so you get immediate fuel for your muscles.
Whereas, Casein Protein, digest slower so you get fuel for your muscles longer.
Of course, keep up your strength training workouts! Good Luck.
