We love finding new ways to work your core. The powerhouse muscle group provides stability and strength for everything from lifting heavier weights to dance cardio, so giving it some extra TLC is never a bad idea.

When was the last time you used a stability ball at the gym? Sure, shiny new gadgets and machinery might look fun, but some machines can be more trouble than they’re worth. Performing basic moves like crunches on an unstable surface, you’ll increase muscle activity when compared to standard crunches. Talk about more bang for your buck!

Pick 3–4 of these exercises and add ‘em onto a cardio day or integrate them into your strength workout. Complete 2–3 sets of 8–12 reps. It’s no bouncy castle, but we guarantee you’ll come around to these core-focused stability ball exercises!
