It's funny. There are so many training modalities nowadays, but back when I first got into exercise the main entry point was bodybuilding. You pretty much looked to see what the bodybuilders were doing and emulated them. Then Crossfit came along and, much like the woman hurling her sledgehammer in that iconic 1984 Apple commercial, smashed the monolithic fitness world into a million fragments.
But one thing I've kept from those bodybuilding days is creatine. It is the most effective performance enhancing supplement other than caffeine. It is well-researched, safe, and legal. Creatine provides the following benefits.
Pretty solid list, huh? The benefits come from creatine's ability to aid in ATP production. ATP is the energy currency used for muscular contractions. As a bonus, it appears to also have neurological benefits that reduce your chances of developing Parkinson's and Alzheimer's. Make sure you get it in the form of creatine monohydrate. Research shows that to be the most effective type. It's odorless and tasteless. Take 5 grams daily, preferably following your workout. Done.
