Side Lunges
The side lunge steps wide to one side, sitting the hips back over the bent leg while the other leg stays long, loading the quads and glutes through a sideways range most training never visits. It builds the lateral strength and inner-thigh flexibility that field sports, tennis and real life all draw on. Coached by Maddy (NASM-CPT) — these are the exact form cues he gives on every client's first week.

Sets & reps by goal
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 4 × 3–6 per side | 2–3 min |
| Muscle | 3–4 × 9–12 per side | 60–90 s |
| Endurance | 3 × 18–27 per side | 45–60 s |
Rep ranges per Helms 2014 · Schoenfeld 2016.
Level — Intermediate
Intermediate — the sideways depth demands inner-thigh mobility that forward lunges never test.
Proper form — 5 cues
- Take a wide sideways step, toes of both feet pointing mostly forward
- Sit the hips back and down over the stepping leg
- Keep the trailing leg straight with its foot flat on the floor
- Track the bent knee over the middle of that foot
- Push hard off the bent leg to return to standing
Breathing: Inhale stepping out and descending, exhale driving back to standing.

How to program side lunges
| Goal | Sets | Reps | Tempo | Rest | RPE |
|---|---|---|---|---|---|
| Strength — entry | 3 | 4-6 per side, bodyweight, paused | 2-1-1-0 | 2 min | 7 |
| Strength — standard | 4 | 3-6 per side, add dumbbells | 2-1-X-0 | 2-3 min | 8 |
| Strength — advanced | 4 | 4-6 per side, heavy goblet hold | 3-1-X-0 | 2-3 min | 8-9 |
| Hypertrophy — entry | 3 | 9-10 per side | 2-0-1-0 | 60-90 s | 7 |
| Hypertrophy — standard | 3-4 | 9-12 per side | 2-0-1-0 | 60-90 s | 8 |
| Hypertrophy — advanced | 4 | 12 per side, 3 s descent | 3-0-1-0 | 90 s | 8-9 |
| Endurance — entry | 3 | 14-18 alternating | steady rhythm | 60 s | 6-7 |
| Endurance — standard | 3 | 18-27 alternating | steady rhythm | 45-60 s | 7-8 |
| Endurance — advanced | 3 | 27+ alternating or 45 s continuous | brisk, form intact | 45 s | 8 |
| Beginner on-ramp — week 1-2 | 2 | 5-6 per side, half depth, hand support | slow, find the groove | 90 s | 5 |
| Beginner on-ramp — week 3-4 | 3 | 6-8 per side, building depth | 2-1-1-0 | 90 s | 6 |
| Deload / technique | 2 | 6 per side, bodyweight, comfortable depth | 3-1-1-0 | 90 s | 5 |
Common questions
What do side lunges work that regular lunges do not?
Regular lunges load the legs front-to-back; side lunges load them sideways, adding serious work for the inner thighs and the hip's lateral stabilizers while stretching the straight leg's adductors on every rep. Most training lives in the forward-backward plane, so the sideways pattern fills a genuine gap.
Are side lunges suitable for beginners?
They sit a step above basic squats and forward lunges because they demand inner-thigh flexibility and sideways knee control at the same time. Beginners can start with a shallow step and limited depth, holding onto a support if needed, and deepen the position as strength and mobility grow together.
How deep should I go in a side lunge?
Only as deep as three checkpoints allow: the bent knee tracking over its foot, the trailing foot flat, and the spine long. For some people that is a quarter-depth position at first, and that is fine — depth earned with control improves steadily, while forced depth just teaches bad positions.
