The almighty basic pushup! This exercise is great for all levels. There are two key factors when performing push ups:

1. Form
2. Range of motion

Regarding form, you want your elbows pointed backward towards your feet as you perform the push up. For standard push ups, your hands should be placed on the floor beneath your shoulders, and slightly wider than your shoulder width. Your core should be inline with your legs and your feet close together.

For range of motion (ROM), you want to start with your arms completely straight and push your shoulder blades apart (imagine pushing your chest away from the floor). At the bottom of the movement you want your chest to get as close to the floor as possible, even better touch the floor (not resting on the floor!). You always want tension in your arms as you perform push ups.

No need to rush your reps. Doing push ups this way will be much harder, but it will also get you much stronger!
