Plyometrics are high-intensity bodyweight exercises that improve power, speed and physical performance. Think of burpees, jumping jacks, plank jacks and box jumps. These movements engage the whole body and raise your heart rate, sending your metabolism into overdrive. During a typical workout, your muscles are stretched and then contracted quickly to produce explosive force.

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.
