To improve your flexibility, the most helpful options from the provided list are:
- Waist bends - This exercise can help stretch the back and sides of your body, improving overall flexibility.
- Hurdler’s stretch - This is specifically designed to stretch the hamstrings and hips, contributing to increased flexibility.
Lunges can also help improve flexibility in the hips and legs, but they primarily focus on strength and stability. Bent-knee push-ups are more of a strength exercise and do not contribute significantly to flexibility.
So, the best choices for improving flexibility would be:
- Waist bends
- Hurdler’s stretch
- Lunges (to a lesser extent)
