Extension knee elastic standing

Purpose of the exercise

Strength exercise for the quadriceps (anterior thigh), knee extensors and core stabilisers. Improves knee extension strength, balance, proprioception and ankle stability. Also effective for developing functional leg strength in standing position and improving single-leg control. Helps recover strength after knee injuries in functional, weight-bearing position.

Supplies

• Resistance band/elastic
• Attachment point at single height (door hook, post, sturdy table leg)
• Wall or chair for balance support (optional)
• Sufficient space to stand and move leg forward
• Flat, stable surface

Starting position

1. Attach the elastic low to a stable point behind you
2. Stand with your back to the attachment point
3. Place the elastic band around your ankle of the leg to be trained
4. Step forward until there is tension on the rubber band
5. Stand on your other leg (standing leg)
6. Bend your working leg slightly behind you (knee bent, about 90 degrees)
7. Keep your torso upright and stable
8. Use light support from wall/chair if needed for balance
9. Tighten your core

Implementation

1. Stretch your knee by moving your leg forward
2. Move in a controlled manner against the resistance of the rubber band
3. Extend your knee as far as possible (ideal: fully extended forward)
4. Keep your upper leg relatively still (especially knee extension)
5. Actively tighten your quadriceps in the end position
6. Hold this position
7. Release controlled back to the starting position
8. Repeat the movement

Points of interest

• ✓ Keep your torso stable and upright throughout movement
• ✓ Move slowly and in a controlled manner
• ✓ Focus on isolation of knee-extension movement
• ✓ Keep your standing leg stable (no wobbling)
• ✓ Actively tighten your quadriceps in a stretched position
• ✓ Breathe calmly during the exercise
• ✗ Avoid swinging or using momentum
• ✗ Don't let the rubber band snap back
• ✗ Don't move your hip too much (focus on knee)
• ✗ Do not lean forward or backward with your torso
• ✗ Don't lose your balance (use support if necessary)
• ✗ Don't force through pain

When this exercise?

This exercise is suitable in later rehabilitation phase after knee surgery or knee injuries when loading in standing position is allowed (in consultation with physiotherapist). Ideal as a progression from the seated/lying version. Very effective for functional strength recovery as it combines balance and proprioception with quadriceps strengthening. Perfect as a home exercise for athletes returning to sport after knee injury. Also valuable as quadriceps activation exercise prior to leg training. Suitable for general leg strength and stability in older people or those with knee osteoarthritis who want to build functional strength. Start with light resistance and build up gradually. For acute knee pain, swelling, instability or balance problems, have it assessed by a physiotherapist first. Use support for balance if needed and build up gradually.
