The calf stretch with a strap is done sitting on the floor with your legs straight out in front. You loop a strap or exercise band around the balls of your feet and pull gently on the ends, drawing your toes back toward you until the backs of your lower legs feel a stretch. It shows up in many programs for tight calves and heel pain, and it suits anyone who finds a standing calf stretch hard to balance in.

How to do the calf stretch with a strap

Sit on a mat with both legs straight out in front of you and your back tall. If your back rounds or the backs of your thighs pull too much, sit with your back against a wall.
Loop a strap, towel or long exercise band around the balls of both feet, as in the video, and hold one end in each hand. The voice guide stretches one foot at a time, which is a fine choice if only one calf needs it.
Keep both knees straight, with the backs of your knees resting down toward the mat.
Pull the ends gently toward you, so your toes and the tops of your feet come back toward your shins. Stop as soon as you feel a stretch in the backs of your lower legs.
Hold the stretch with your shoulders relaxed and your breathing slow, then ease off the strap and let your feet relax.

What you should feel

A steady pull in both calves, sometimes spreading up behind the knees. A mild pull in the backs of the thighs is common too. You should not feel sharp pain at the back of the heel or pinching at the front of the ankle.

Common mistakes

Yanking on the strap or bouncing, instead of pulling slowly and holding.
Bending the knees, which takes much of the stretch off the upper calf.
Leaning back so your body weight does the pulling rather than your arms.
Hunching your shoulders up toward your ears as you pull.

How often

Many programs use holds of 20 to 30 seconds, repeated 2 to 4 times, once or twice a day. Your physio will adjust this.

Stop and check with your physio if

Sharp pain at the back of the heel or in the Achilles tendon.
Your calf or thigh becomes swollen, warm, tender, red or darker than usual, or has a throbbing or cramping pain that feels different from normal muscle ache. Stop and get medical advice the same day, as this can be a blood clot. If you are also short of breath or have chest pain, call emergency services.
Tingling, numbness or pain that runs down the back of your leg into your foot. Ease off, and if it comes back each time, ask your physio before you carry on.
A sudden pop or snap at the back of your ankle or heel, a feeling that someone kicked you there, or sudden pain there after which you cannot push off or rise onto your toes on that leg. Stop, take the weight off that leg carefully and go to an urgent care center or emergency department the same day, even if you can still walk, as this can be a torn Achilles tendon.

From the clinic

With your knees straight, the stretch mainly reaches the bigger calf muscle (gastrocnemius). The deeper calf muscle (soleus) stretches more with the knee bent, which the soleus stretch covers. If sitting with straight legs bothers your back, the standing calf stretch works the same muscles while you stay on your feet. Sitting with your legs straight and your feet pulled back also stretches the nerve that runs down the back of the leg, so if you have sciatica, the standing version is often the more comfortable choice.

After a torn Achilles tendon, whether or not it was repaired, calf stretching is usually avoided for the first months, because stretching can lengthen the healing tendon. Follow your surgeon's or physio's plan on when to start. After a recent ankle fracture, check with them first too. If you use an exercise band, look it over for small tears first and keep a firm grip on the ends, because a band that slips off your feet can snap back toward your face.

If you have had a hip replacement, get the go-ahead from your surgeon or physio before you try the calf stretch with a strap. Getting down to the floor and back up bends the hip well past a right angle, and many surgeons ask you to avoid that for the first months after some operations. Until you are cleared, the standing version keeps you off the floor.
