Although they get a bad rap as being too basic, situps are an effective way to target your abdominal muscles. If you have lower back problems, stick with a crunch, which requires just your upper back and shoulders to lift off the ground.
Start by lying on the ground on your back with your knees bent, feet flat, and your hands behind your head.
Keeping your feet glued to the ground, begin to roll up from your head, engaging your core throughout. Don’t strain your neck during the upward motion.
When your chest reaches your legs, begin the controlled phase back down to the starting position.
