Park, beach, or home, gym, no equipment necessary to strengthen your core…abdominals, back, and shoulders! Use about 30 second hold times, up to 3-4 reps. Please keep in mind planks are not recommended for those with shoulder pain/injuries. As with any exercise, you should feel not pain in you neck, back or anywhere else in your body. If you do, stop the exercise. We need find modifications for you.
Let me know where you do your planks.
