Legs
Single-Leg Lunge with Kettlebell:
Improve lower body stability and calf definition through controlled unilateral lower body volume.
How to perform.
Follow the sequence — setup is half the lift.
Stand upright while holding a kettlebell in the hand opposite of your leading leg.
Step one foot forward and lower your hips until both knees are bent at approximately a 90-degree angle.
Shift your weight slightly onto the ball of the front foot to engage the calf throughout the movement.
As you descend, perform a controlled heel raise with the front foot at the bottom of the lunge.
Lower the front heel back to the floor before driving through the midfoot to return to the starting position.
Complete all repetitions on one side before switching the kettlebell to the other hand and repeating with the other leg.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Allowing the front knee to collapse inward during the descent.
- Rushing the heel raise which reduces tension on the calf muscle.
- Leaning too far forward and losing spinal alignment.
- Using a kettlebell that is too heavy to maintain balance.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
