A few things to know about whey it's one of the most easily digestible protein sources out there, contains key amino acids, and is packed full of antioxidants. What does all this mean Well, pretty much that Hammer Nutrition's Whey Protein Powder is one of the best ways to help your body recover after hard exercise. The protein replenishes the stores that are depleted after two hours or so of activity, the amino acids help repair small muscle tears and fight off soreness, and the antioxidants help eliminate the free radicals that are produced when you're out riding, running, or adventuring. Since whey proteins are easy for the body to assimilate and whey is nearly 100% protein, it's one of the most efficient ways to refuel after a hard workout. Bonus: it tastes good, so you won't have to force yourself to choke it down.
