4. Modified Push-Up
Bring hands below shoulders and knees back but still on the ground, then lift feet to begin in a modified push-up position. Keep spine neutral and head lifted. Inhale. Bend elbows back and on a slight diagonal to target the triceps as well as the chest. Exhale and press back up. Repeat at your own pace for 1 minute. Tip: If your lower back sags, opt for a smaller range of motion and just bend at the elbows without bringing chest down to the floor.
Works: Chest, triceps, and core, including your diaphragm + steadily increases HR. Heart rate will begin increasing steadily.
