The side split squat is a bodyweight lower-body exercise that loads one leg at a time by shifting your weight laterally while keeping the opposite leg straight. It targets the quadriceps and inner thighs (adductors), with the glutes contributing to stability, making it an effective tool for building unilateral leg strength and hip mobility.
How to do the Side Split Squat
- 1Stand with your feet significantly wider than shoulder-width apart, toes pointing forward or angled slightly outward.
- 2Place your hands on your hips or extend them in front of you for balance.
- 3Brace your core and keep your chest tall throughout the movement.
- 4Shift your weight to the right side by bending your right knee and pushing your hips back and down toward your right heel.
- 5Lower until your right thigh is roughly parallel to the floor or as deep as your mobility allows, keeping your right knee tracking over your toes.
- 6Keep your left leg straight with the left foot flat on the floor, feeling a stretch through your left inner thigh.
- 7Push through your right foot to straighten your right leg and return to the starting wide stance.
- 8Repeat for the desired reps on the right side, then switch to the left side.
Form tips
- Keep your working-side knee tracking in line with your middle toe — let it travel forward naturally rather than caving inward.
- Sit back into the movement as though reaching for a chair; this loads the glutes and quadriceps rather than stressing the knee.
- Keep the foot of your straight leg fully flat on the floor to protect your knee and maximize the adductor stretch.
- Move slowly on the way down — a 2–3 second descent builds more strength and improves hip mobility over time.
- If balance is difficult, hold a doorframe or squat rack with one hand until you build the stability needed to go hands-free.
Common mistakes
- Allowing the working-side knee to cave inward, which stresses the knee joint and reduces muscle activation in the quads and glutes.
- Rising onto the toes of the straight leg, which shifts load away from the inner thigh and reduces the stability of the movement.
- Rounding the lower back or collapsing the chest forward, which places unnecessary spinal load and makes it harder to reach full depth.
- Rushing through reps with momentum, which bypasses the muscle tension that makes the exercise effective and increases injury risk.
- Using a stance that is too narrow, which limits the range of motion and reduces the adductor stretch that makes this movement unique.
Frequently asked questions
What muscles does the side split squat work?
The side split squat primarily targets the quadriceps of the bent leg and the adductors (inner thigh muscles) of both legs. The glutes also engage to control the descent and drive you back up.
What is the difference between a side split squat and a lateral lunge?
They are nearly the same movement. The side split squat typically starts from a fixed wide stance and you shift weight side to side, while a lateral lunge often involves stepping out to the side from a standing position. Both work the same muscles.
Is the side split squat good for beginners?
Yes. Since it uses only body weight and allows you to control your depth, it is accessible for beginners while still being challenging enough for intermediate lifters. Start with a shallow range and increase depth as your hip mobility improves.
How do I make the side split squat harder?
Once body weight feels easy, add difficulty by holding a dumbbell or kettlebell at your chest, slowing your tempo, or pausing for 2 seconds at the bottom of each rep.
How many sets and reps should I do for the side split squat?
For most people, 3 sets of 8–12 reps per side works well for building strength. If your goal is mobility and muscle endurance, try 2–3 sets of 12–15 reps with a slow, controlled pace.
