“What I get most from the program is a way to recover from a workout or a game and then to accelerate the recovery,” says safety Malcolm Jenkins, who earned his first trip to the Pro Bowl in the 2015 season. “I used to do what everyone else did – cold tubs when you’re sore, for example. We have a lot more to do to recover and it helps. I’ve learned about nutrition and the benefits there. The sleep aspect is huge. I used to average about six to seven hours a night and I’m to probably seven to eight hours and it’s definitely made a difference for me.”

Wide receiver Chris Givens played for four seasons in St. Louis and Baltimore before signing with the Eagles as an unrestricted free agent this offseason. He had heard of the Eagles’ Sports Science program and he was open to advice on how it could improve his performance. So he presented something he had noticed throughout his career - his left leg always seemed stronger than his right leg. That’s just the way it was. He never thought much about it, but now he was wondering and decided to see what Huls and his team had to say.

What he found out surprised him: It wasn’t just that his right gluteal muscles were weaker, but that they were not firing as effectively as the muscles in his left gluteal. Huls and his staff immediately put Givens on a program to strengthen the muscles in his right leg and Givens noticed the difference.

In a big, big way.

“Since I started working with Shaun in April, I’m light-years ahead of where I’ve ever been on the field,” Givens says. “I had always just figured one leg was stronger than the other. I never knew it could be broken down the way it has been and I’m moving so much better on the field. It’s a huge difference. We did a lot of exercises for each leg, we did things that activated my glutes, we did things to strengthen my adductor muscles. I don’t know the names of the exercises but, I know that once my glutes were firing correctly, everything fell into line for me.”
