STRAIGHT LEG RAISE INSTRUCTIONS
1. Lie on your back with your hands by your sides or underneath your glutes. Keep your legs straight or just slightly bent.
2. Raise your legs until your body is in an L shape.
3. Pause, lower both legs slowly and then return to the starting position.
4. Repeat until set is complete.
PROPER FORM AND BREATHING PATTERN
When doing the straight leg raise, keep your abs engaged at all times and keep your back, head and shoulders pressed against the floor. Breathe in as you lower your legs and, if you feel any discomfort on your lower back, reduce the range of motion by lowering your legs only half-way.
Adding the straight leg raise to your workout routine helps to increase the strength and definition of your abs and also improves your overall flexibility and stability.
SETS AND REPS
Start with 2 or 3 sets of 8 to 12 repetitions and increase this number over time, until you’re able to complete 3 sets of 25 to 50 repetitions. You can also create a bigger challenge by adding leg weights or increasing the range of motion.
