Step Up
The Step Up is a strength exercise with dumbbells for your quads. Share of the load in the Zulta muscle model: gluteus maximus 22%, quads (vastus lateralis) 18% and quads (vastus medialis) 18%.
Also known as: box step up, weighted step up

How to do it
- Hold a dumbbell in each hand and face a box or bench about knee height.
- Put one foot flat on the box with the whole sole in contact.
- Push through the heel on the box and stand up straight on top.
- Step the other foot back down slowly, keeping the lead foot on the box.
- Complete all reps on one leg before switching.
Tips
- Keep the chest up and a slight forward lean at the start.
- Control the lowering instead of dropping to the floor.
Common mistakes
- Hopping off the floor foot.
- Rounding the back as you lean forward.
- Knee on the box drifting inward.
