Fire Hydrant
The Fire Hydrant primarily works the Gluteus Medius, Gluteus Minimus, with secondary activation of the Tensor Fasciae Latae and stabilizer support from the Rectus Abdominis. It is a bodyweight isolation exercise at beginner difficulty.
The Fire Hydrant is an beginner isolation exercise requiring no equipment, following a flexion movement pattern. It primarily targets the Gluteus Medius, Gluteus Minimus, with secondary engagement of the Tensor Fasciae Latae. As a unilateral push, each side is trained independently for balanced development.
On hands and knees, raise one knee out to the side.

Muscles Worked
The Gluteus Medius, and Gluteus Minimus are the primary movers, collectively driving the movement and absorbing the greatest share of the load. The Tensor Fasciae Latae assists as a secondary mover, contributing to force production without bearing the primary load. The Rectus Abdominis act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Gluteus Medius (glutes)
- Primary Muscle Gluteus Minimus (glutes)
Secondary Muscles
- Secondary Muscle Tensor Fasciae Latae (hip_flexors)
Stabilizer Muscles
- Stabilizer Muscle Rectus Abdominis (core)
How to Perform
Preparation
- Position body with proper alignment.
Execution
- Contract target muscles to move through full range of flexion.
- Return to starting position under control.
- Repeat.
Comments
- Perform equal reps on each side.
Tips & Common Mistakes
- Control the eccentric phase — the lowering portion drives significant muscle development.
- Avoid momentum; focus on feeling the target muscle work through the full range.
- Full range at both ends maximizes stretch at the bottom and contraction at the top.
Programming Suggestions
Adapt your sets and reps to your training goal. As a beginner-friendly exercise, start with lighter loads and focus on form before progressing weight.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Gluteus Medius, Gluteus Minimus) and can be substituted based on your equipment or variation preferences.
