Your core muscles include those in your lower back, hips, pelvis and abdomen. The purpose of sit up exercises is to strengthen these muscles and help them work effectively in tandem with one another. Stronger core muscles are supposed to help alleviate or even avoid back pain. They should also decrease muscle spasms, protecting your back against injury. Sit ups ARE NOT an effective way to achieve these goals. #RSfitnessLA . #RSfit #RSFitness #workhard #losAngeles #fitlife #westHollywood #exercise #dedication #asmeninistreneris #trainer #coach #squat #hollywood #fitspo #yoga #RSfitClubLA (at Los Angeles, California) https://www.instagram.com/p/BxrBP9OHHHt/?igshid=jiot61426t5e
