How to do it: With your bar on the floor in front of you, place your feet slightly narrower than hip-width apart. Make sure the bar is as close to your shins as possible, and position your hands on the bar, just outside your shins. With your shins perpendicular to the floor, flex your hamstrings and lift your butt up and back, extending your legs so they’re nearly straight, with only a slight bend in the knee. Slide the bar up and toward the shins. Then, bend your knees slightly and proceed to lift the bar all the way off the floor in a straight line. Extend your hips fully at the top and stand tall with neck relaxed, arms straight. Pinch your shoulder blades together, squeezing your abs and glutes. Keeping the bar close to your body and with a straight back, reverse the movement. That’s one rep.
A sedentary lifestyle can lead to having weak and tight hip flexors as they are always in the shortened position. Tight hip flexors can lead to a limited range of motion, poor posture, lower back and hip pain, and even injuries. These muscles need to get a workout when you are standing and doing movements such as raising your leg to climb stairs, run, or ride a bicycle.
