6.BARBELL STRAIGHT LEG SIT-UP
A “next-level” sit-up, the barbell straight leg sit-up will keep your spine in a healthy position throughout the exercise.
To start, lie on your back with your legs straight holding a barbell overhead, hands shoulder-with apart. Keeping you arms straight and above your head and lift your torso until you’re sitting straight up.
Use the barbell without any weight to start with to ensure you perform the exercise with proper technique. Once you get used to the movement it’s down to you whether you add weight or increase the rep range.
