## How to do the Single Leg Step-Up

1. Stand facing a box with a dumbbell in each hand, placing one foot firmly on top.
2. Step up onto the box by pushing through your planted foot.
3. Bring your free leg up gently, avoiding a push from behind.
4. Carefully lower back down, keeping your body controlled and balanced.

### Full technique — 8 steps

1. Stand facing a box or bench, holding a dumbbell in each hand, with one foot placed fully on top.
2. Set the working foot flat and keep the whole foot in contact with the surface.
3. Lean slightly forward over the front leg and keep your hips square.
4. Drive through the planted foot to raise your body onto the box.
5. Bring the trailing leg up without pushing hard off the floor behind you.
6. Stand tall on the box with the working leg fully extended.
7. Lower back down under control until the trailing foot returns to the floor.
8. Complete all reps on one side before switching legs.

## Common mistakes

- Pushing off the trailing foot
- Front heel lifting off box
- Knee collapsing inward
- Using a box too high
- Dropping quickly on descent

## Form cues

- Push through whole foot
- Minimize back-leg push
- Keep hips level
- Stand tall at top

## How much to do

- **Strength** (good fit): 4–5 sets of 5–6 reps · rest 2 min 30 s · 1–2 reps in reserve · lower 2 s, lift 1 s
- **Muscle growth** (good fit): 3–4 sets of 8–12 reps · rest 1 min 30 s · 2–3 reps in reserve · lower 2 s, lift 2 s
- **Endurance** (best fit): 2–3 sets of 15–20 reps · rest 1 min · 3–4 reps in reserve · lower 2 s, lift 2 s

Reps in reserve: how many more you could still do when you end the set.
