Pushups are a challenging bodyweight exercise that develops the triceps, shoulders and core. Aim to do as many pushups as you can in one session for a total of two to three sets with rest in between. You can modify a full pushup position by starting on your knees rather than your toes. Do pushups by lying face-down on the floor. Prop yourself up so that you are on your hands and knees, with your body forming a straight line from head to toe. Your hands should be underneath your shoulders. Keep your abdominals engaged as you lower toward the ground and push back up into start position.
Get in plank position with your hands wider than shoulder-width apart (A). Lower your chest as close to the floor as you can. Holding that position, lift your right knee to the outside of your right elbow (B). Return to plank position, then push back up to start; repeat on the other side. That's one rep. Do three sets of 12 to 15 reps, resting for 30 seconds between sets.
Back to the tricep pushups and really activating those tricep muscles for toned arms.  If you need a rest, that's totally cool. Just take a break in the up position and maintain that plank form. This way you are still working your arm muscles just by holding your body weight up. So that's totally fine for some of our beginners out there. For those who are more advanced, we want you going as hard as you can and trying to hit that 15 to 20 reps. You're doing great.
