Push-ups are a mainstay of upper-body workouts. You'll find them in most workout plans but, despite what some personal trainers suggest, they are actually not the easiest exercise to do.
A push-up requires strong shoulders, arms, back, and core muscles, which need proper training. The good news is that you can build up to doing a push-up slowly and strengthen these areas without dumbbells or kettlebell weights. Once you've done one, you'll find it easier to add repetitions in a general strength training program for women.
