Pushups
Muscles worked: Chest, shoulders, abs and triceps
When doing a pushup, your body should be like a plank which means that you have to tighten your leg and core muscles; this provides a good secondary workout for your core. The primary muscle group worked that you use during the movement of a pushup is your chest, but your shoulders and triceps play a role as well. Pushups are a tried and true exercise that offers a great way to challenge your body, while using your body weight and gravity to create resistance. If a traditional pushup is too challenging for you to properly perform, then try elevating your upper body by stabilizing your hands on a flat bench. This will reduce the amount gravity, or resistance, allowing you to adjust the difficulty without changing your body positioning like a regression from your feet to knees does. Of course, if a pushup from your knees is what works for you there is nothing wrong with that either! Keep doing your pushups, and as you get better at doing them, find ways to challenge yourself with slower reps or explosive reps with hand claps.
