Target: hamstrings, glutes, core

Why it works: This targets the smaller stabilising muscle responsible for keeping your joints in line. Because you’ve done a heavy-lifting exercise before this one, your larger leg muscles will be fatigued. This places greater load on the stabilisers and increases the move’s effectiveness.

• Stand on your right leg with your left shin parallel to the ground and arms at your sides.
• Brace your core and slowly lower yourself as far as you can go, keeping your shoulders back and looking straight ahead.
• Drive back up and retract your shoulder blades at the top.
