Lead by motivational Curves Coach, MyCurves On Demand replicates your whole in-club Curves workout, including abdominal and core exercises like Crunches. This essential core move is similar to a situp but as Crunches are an isolation exercise, they focus on your abdominals while also strengthening the erector spinae, which are the muscles along your spine that assist with good posture. Watch the video tutorial below to learn how to do Crunches safely and be sure to check out MyCurves On Demand for more core exercises and full-body workouts!
