Your core is the foundation for all your body’s movement, and weak abdominal and lower back muscles can make you more prone to injury. In fact, about 8 in 10 of us will experience back pain at some point in our lives.
To help build a stronger core, try this straight-leg raise today: Lie on your back with your arms at your sides, legs extended. Keeping your right leg straight, lift it toward the ceiling until it’s perpendicular to your torso, exhaling as you do so, then lower it back down, inhaling. Lift and lower the left leg next. That’s one rep; do 10 total. (To make the move more challenging, you can lift both legs at once—but avoid this if it bothers your lower back.)
