M Square Fitness on Instagram: "Many people do leg raises wrong — only moving from the hips. ❌ That just works your hip flexors, not your abs. ✅ To target abs, you need trunk flexion → curl your spine and lift glutes. Bonus: you can bend your knees to reduce hamstring stretch. Try the hanging leg raise or bench version for best results. #abworkout #legraises #coretraining"
