Change your thoughts and you change your world. – Norman Vincent Peale
If you want to look fit like a superhero:
You need to have a strategy. It is all inclusive. Not a single tactic works alone. You need to encompass everything.
You need to eat right. No sugar.
You need to exercise right. Strength training. Isolation. Cardio when necessary.
You need to take the right supplement.
You need to have enough rest.
Always work hard, and always believe in yourself.
