Introduction
Exercise: Leg Raise Alternating (LRA)
The Leg Raise Alternating (LRA) is a core strengthening workout that targets the lower abdominals specifically. This exercise helps improve posture, stability, and balance by working on the rectus abdominis muscles. It's an effective exercise for building a defined midsection, particularly useful in achieving a six-pack appearance while also enhancing functional fitness.
Muscles Worked
- Primary: Lower Abdominals (Rectus Abdominis, Transversus Abdominis)
- Secondary: Hip Flexors (Iliopsoas), Obliques (External and Internal Oblique)
How to Do It (Step-by-Step)
- Lie flat on your back with your legs fully extended and arms at your sides.
- Lift your left leg off the ground, keeping it straight, until it's perpendicular to the floor.
- Lower your left leg slowly and simultaneously lift your right leg to the same position. Alternate lifting each leg in a slow and controlled manner.
Tip: To avoid straining your lower back, keep your abs engaged throughout the exercise and maintain a neutral spine.
Rep & Rest Guidelines
- Strength: 4–6 reps, 2–3 min rest
- Hypertrophy: 8–12 reps, 60–90 sec rest
- Endurance: 12–20 reps, 30–60 sec rest
