I Do CrossFit and These Are the 10 Bodyweight Exercises I Do For Strong Arms

Why I do it: I love exercises that make my muscles quiver, and this is one of them. We often hold this for 30 seconds in class, but I also like doing hip dips in this position.

• Start on the floor, resting on your forearms and knees.
• Step your feet out one at a time, coming into plank position on your elbows.
• Contract your abs to prevent your hips from sticking up or sinking. Your spine should be parallel to the floor, with your abs pulling toward the ceiling.
• Hold for 30 seconds and work your way up to one minute as you get stronger.
