Active vs. Passive Flexibility: Mind the Gap

Students compare how far a leg or arm goes with their own strength versus with help from a towel. They discover the difference between active and passive flexibility and how to close the gap.

How to play

1. Explain: passive flexibility is with help; active is with your own muscles only. Demo with a lying leg raise (3 min).
2. Hamstrings lying down: raise the straight leg without help and notice the height, then use the towel to assist (4 min).
3. Shoulders: lying face down, raise the arms without help, then with a towel held in both hands, pulling gently (4 min).
4. Closing the gap: lift the leg to the highest active point and hold 5 seconds, 3 reps per side (6 min).
5. Each student sets a personal goal and writes it down, without comparing with anyone (3 min).

Rules

• No one measures or compares results with others.
• The towel pulls gently, without pain.
• Keep knees straight only as far as is pain-free.
• Work slowly and breathe normally.

Variations

Adaptations

• Wheelchair users: compare shoulders and elbows while seated.
• Hypermobile students: focus on active control, not on gaining passive range.
• Students with visual impairments: the partner uses a hand as a height reference, lightly touching the leg.

Learning goals

• Tell active and passive flexibility apart.
• Use exercises that improve control at long ranges.
• Set a personal flexibility goal without comparing.

Equipment for a class of 25

• mats: 30
• towels: 30

Teacher tip

A long resistance band or rope can replace the towel. The classic mistake is bending the knee and rolling the hip to lift higher: ask students to keep the bottom leg flat on the floor.
