Perfect this fundamental bodyweight exercise that builds chest, shoulders, triceps, and core strength with zero equipment. Push-ups are scalable from wall pushes (beginners) to one-arm variations (advanced), making them perfect for any fitness level. Proper form matters: hands shoulder-width, body straight like a plank, chest touches ground, full extension at top.
Follow a progression program like '100 pushups' or start with 3 sets of your maximum. Train 3-4 times weekly, rest between sets, and watch your numbers climb. Benefits extend beyond strength—improved posture, bone density, and functional fitness for daily activities. No gym needed.
