Elsa Pataky's trainer, Fernando Sartorius, says that focusing on squeezing your glutes while performing a booty-blasting exercise allows you to activate the muscle group to their maximum potential. Cameron Diaz's trainer, Teddy Bass, founder of the trademarked booty-sculpting program called Rock Bottom Body, says you should get into a bridge position and memorize what it feels like to really engage your buns—and then try to feel that burn every time you work your butt. The point: Thinking about squeezing your glutes (and actually squeezing them) while strength-training helps you work the muscles in your butt harder.
In addition to adequate protein, you need more calories (your protein intake contributes to your total caloric intake, so these two go hand in hand). Use the following formula to calculate the number you need to take in daily to gain one pound a week, and break down your diet using the macro guidelines listed above. (Give yourself two weeks for results to show up on the scale. If you haven't gained by then, increase your calories by 500 a day.)
Firstly, let’s establish where your glutes are and what they actually refer to! Your ‘glutes’ — or your gluteal muscles, as they are more formally known — refer to the muscles in your butt. Specifically, there are three major muscles in this area: your gluteus maximus (the main, large muscle that shapes your backside), your gluteus medius and your gluteus minimus (two smaller muscles that assist the gluteus maximus in moving your body).
