The pushup is one of the most basic but effective moves for strength and conditioning.

This humble muscle-building exercise trains the muscles in your chest, shoulders, triceps, and abs. Add the slightest tweak and that burn can quickly shift from a killer chest pump to a brutal ab ripper. While there are countless variations—some of which require near-superhuman strength—these modifications are suitable for both beginner and intermediate athletes.
