Targets shoulders, chest, arms, and abs. In place of "gliding disks" you can use paper plates on carpet or a towel on hardwood.
Step 1: Start on floor in straight arm plank position, palms on one end of mat, forefeet on gliding disks (paper plate or towel).
Step 2: Keeping legs steady, walk hands forward 4 steps.
Step 3: Lower onto forearms, one arm at a time.
Step 4: Crawl backward on forearms toward opposite end of mat, legs steady.
Step 5: Once you reach your starting position, return to full plank (rising onto palms)
Step 6: Repeat.
MAKE IT EASIER: Start in modified push-up position with knees rather than feet on disks.
