Single-Leg Squat Touchdown
The Single-Leg Squat Touchdown is a dynamic single-leg balance and stability exercise that challenges proprioception, ankle mobility, and lower body control through touchdown-assisted single-leg squatting. This intermediate progression is ideal for individuals building toward full single-leg squat capability or seeking improved balance and stability with less demanding movement. The exercise develops ankle and hip stability while testing balance and proprioceptive awareness.
NASM’s evidence-based approach emphasizes balance training for improving stability, proprioception, and injury prevention. The single-leg squat touchdown improves dynamic balance, ankle stability, proprioceptive awareness, and serves as an effective progression toward full single-leg squat achievement.
How to Perform a Single-Leg Squat Touchdown
Step 1: Setup
Stand on one leg with weight distributed evenly across your foot. Position the non-working leg slightly forward or to the side and prepare for a balance challenge.
Step 2: Brace/Position
Engage your core and prepare for descent. Focus on maintaining upright posture and keeping your weight centered over your planted foot.
Step 3: Execute/Drive
Lower your body into a single-leg squat, descending until the toes of your non-working leg lightly touch the floor for balance assistance. The touchdown should provide minimal support while maintaining most weight on the planted leg.
Step 4: Return/Descent
Drive through your planted leg to stand back up, maintaining balance throughout. Reduce reliance on the touchdown as strength and balance improve. Complete all repetitions on one leg before switching sides.
Muscles Worked
Primary Muscles:
- Quadriceps -- primary mover for knee extension and single-leg support
- Glutes -- assist in hip extension and provide lateral stability
Secondary Muscles:
- Hip Stabilizers
- Hamstrings
- Core Stabilizers
- Ankle Stabilizers
Common Mistakes
- Placing too much weight on the touchdown leg, which defeats the purpose and reduces single-leg stimulus
Allowing the planted knee to cave inward (valgus), which indicates poor hip stability
Leaning excessively forward, which shifts weight distribution and reduces quadriceps engagement
Jerky movements, which indicate inadequate stability or strength for the exercise
Not progressing toward full single-leg squat, which stalls balance development progress
Single-Leg Squat Touchdown Variations
As part of NASM's evidence-based approach to movement and strength training, the single-leg squat touchdown reinforces proper movement mechanics essential to long-term performance and injury prevention. NASM-certified personal trainers use the Optimum Performance Training (OPT) model to integrate exercises like the single-leg squat touchdown into individualized programs based on each client's assessment results.

FAQs
How does single-leg squat touchdown differ from a full single-leg squat?
The touchdown provides assistance at the bottom of the movement, reducing demand on balance and stabilizer muscles. This variation serves as a progression bridge, allowing gradual strength and balance development before attempting full single-leg squats without assistance.
When should the touchdown assistance be minimized or eliminated?
As balance and strength improve, gradually reduce pressure on the touchdown foot, moving from significant support to minimal contact. Once you can perform single-leg squats with light fingertip contact only, progress to full single-leg squats without any external support.
What if balance and stability remain poor despite practicing this exercise?
If balance improvements plateau, focus on ankle mobility and hip stabilizer strengthening through supplementary exercises. Incorporating single-leg balance holds, foam rolling, and proprioceptive training helps develop the foundational stability needed for single-leg squatting.
