Kneeling Hip Flexor is an isolation exercise for the legs: one joint works, so it comes after the compound lifts to finish the target muscle. Secondary muscles: glutes, core. Equipment: bodyweight. Difficulty: beginner, suitable for beginners. It takes 5 steps; the most common mistake is covered in the tip below.
Step-by-step
- Kneel on one knee with the other foot in front, bent at 90 degrees
- Keep your torso tall and squeeze the glute of the back leg
- Push your hips gently forward
- When you feel the stretch at the front of the back hip, hold for 30-45 seconds
- Switch sides and repeat

How to program it
Sets × reps and rest by goal; tempo and controlled reps matter most on isolation work. Start at the bottom of the range in week one; add 2.5–5% when you hit the top with clean form.
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 3 × 6-8 | 120 s |
| Muscle gain | 3 × 10-15 | 75 s |
| Fat loss / conditioning | 3 × 12-15 | 60 s |
