Side Tuck And Leg Raise Tutorial
Side tuck and leg raise is a seated, side-focused abs exercise where you balance on one hip, tuck your knees in, then extend and swing your legs diagonally forward.
It targets the obliques and deep core while also challenging balance and hip control. This move is great for people looking for a how to do side abs exercise that uses no equipment and fits well into core circuits.
Focus on controlled movement, steady breathing, and keeping your torso tall as your legs move. It works best for intermediate trainees, but beginners can scale it down.
Benefits
- Strengthens the obliques
- Improves core coordination
- Builds hip control and stability
- Challenges balance without equipment
- Great addition to abs circuits
Setup & Starting Position
Start by sitting on the floor with your body angled slightly to one side, resting primarily on one hip. Your torso should be upright, not slouched, with your chest open and shoulders relaxed.
Place both hands on the floor for support, slightly behind and to the side of your hips. Fingers can point away from your body or slightly outward, whichever feels more comfortable for your shoulders.
Extend your legs out in front of you at a diagonal angle, keeping them together. From here, lightly lift your feet off the floor so your core is engaged before the first rep begins.
Setup tip: Think about growing tall through the spine before lifting your legs, this makes it easier to control the movement.
How To Do Side tuck and leg raise (Step-by-step)
- Sit balanced on one hip with hands planted on the floor.
- Lift both feet off the ground with legs together.
- Tuck your knees in toward your chest with control.
- Keep your torso tall and chest lifted.
- Extend your legs out and swing them diagonally forward.
- Pause briefly at full extension.
- Slowly draw the knees back into the tuck.
- Repeat for the desired reps before switching sides.
Form Cues
- Stay tall through the spine
- Move the legs, not the shoulders
- Keep feet together
- Control every rep
- Press hands gently into the floor
- Engage core before lifting
Breathing & Bracing
Proper breathing helps you stay balanced and keep tension in your core during the side tuck and leg raise.
Before lifting your legs, take a small inhale through your nose and gently brace your abs as if preparing for a cough. As you tuck your knees in, exhale slowly through your mouth while keeping your ribs pulled down.
Inhale again as you extend and swing the legs forward, then exhale as you return to the tuck position. The breathing should feel smooth and rhythmic, not forced.
A simple pattern to repeat is inhale to extend, exhale to tuck. Avoid holding your breath, and keep the tension focused around your waist rather than pushing your belly outward.
Common Mistakes
- Leaning back too far, fix by sitting taller and engaging the abs.
- Using momentum to swing the legs, fix by slowing the movement.
- Letting feet separate, fix by squeezing legs together.
- Locking the shoulders, fix by relaxing and pressing gently through hands.
- Rounding the lower back, fix by lifting the chest.
How It Should Feel
Quick self-check: You should feel steady tension along the side of your abs and deep in your core.
Good signs:
- Burning sensation in the obliques
- Controlled leg movement without swinging
- Balanced pressure through hands and hip
Warning signs:
- Sharp pain in the hip or spine, stop immediately
- Neck strain from leaning back too far
If you feel it mostly in your lower back, shorten the range of motion and focus on bracing your abs before moving. If the neck feels tense, lift your chest and reduce how far you lean.
Variations
Easier
- Feet-tap side tuck, keep heels lightly tapping the floor between reps.
- Partial extension, extend legs only halfway instead of fully.
Harder
- Straight-leg side raise, keep legs straight throughout without tucking.
- Slow tempo reps, pause 2 to 3 seconds at full extension.
Sample Workout
Core-focused bodyweight workout:
- High plank, 30 seconds
- Side tuck and leg raise, 10 to 12 reps per side
- Dead bug, 10 reps per side
- Side plank, 20 to 30 seconds per side
Rest 45 to 60 seconds and repeat for 2 to 3 rounds. Use this exercise mid-workout when your core is warm.
Progression Plan
Week 1: Perform 2 to 3 sets of 8 to 10 reps per side. Keep the movement slow and focus on balance and posture. Rest 60 seconds between sets.
Week 2: Increase to 10 to 12 reps per side and add a brief pause at full extension. Reduce rest to 45 seconds if form stays solid.
Week 3: Try straight-leg reps or slower tempo, taking 3 seconds to extend and 3 seconds to return. Perform 3 sets.
Move to advanced variations once you can complete all reps without momentum or loss of balance. Repeat a week if form breaks down or if you feel excessive strain in the lower back.
