Thomas Test
The Thomas Test assesses hip flexor tightness and overall hip mobility.
- Lie on your back at the edge of a table or bench.
- Pull one knee towards your chest while keeping the other leg extended.
- Observe the position of the extended leg; it should remain flat on the table.
- Note any elevation of the extended leg, indicating tightness in the hip flexors.
How to perform the Thomas Test
- Set up. Set up in a stable, balanced starting position appropriate for the Thomas Test using your body weight.
- Brace and execute. Brace your core, control the descent, and move through a full pain-free range of motion while emphasizing your primary working muscles.
- Reset. Reverse the movement under control and reset between repetitions, keeping your form crisp on every rep.
Coaching cues
- Move with intent — every rep should feel deliberate, not rushed.
- Drive force through your working muscles rather than momentum.
- Keep your breathing steady: exhale on the hard part, inhale on the reset.
Common mistakes
- Using too much weight and losing positional control.
- Cutting the range of motion short and missing the target muscle.
- Letting your spine round or hyperextend instead of staying neutral.
Detailed cues, common mistakes, and demonstration video are available in the Fitly app.
