The assisted standing triceps extension with a towel is a bodyweight, self-assisted upper-arm exercise that targets the triceps brachii. Standing tall, you drape a towel behind your back and let the lower arm pull against the working arm to add resistance and depth through the overhead extension. It is an accessible way to train the triceps and open the back of the upper arm with no machines or free weights.

How to do the Assisted Standing Triceps Extension (with towel)

  1. 1Stand tall with your feet about hip-width apart, core braced and chest up.
  2. 2Hold one end of a towel in your working hand and raise that arm overhead, bending the elbow so your hand drops behind your head.
  3. 3Reach your other hand behind your lower back and grasp the hanging end of the towel.
  4. 4Take up the slack so the towel is taut between both hands, with the working elbow pointing toward the ceiling.
  5. 5Extend the working arm by straightening the elbow, lifting the lower hand slightly as the towel feeds upward.
  6. 6Squeeze the triceps at the top, keeping your upper arm still and close to your head.
  7. 7Lower under control, letting the lower hand gently pull the towel back down to stretch the triceps.
  8. 8Complete your reps, then switch the towel to the other side and repeat with the opposite arm.

Form tips

  • Keep the working upper arm fixed beside your head so the movement happens only at the elbow.
  • Use the lower hand to set the resistance — pull harder for a tougher rep, ease off for an assisted, lighter one.
  • Move through a full range of motion, fully straightening at the top and feeling a stretch in the triceps at the bottom.
  • Keep your ribs down and avoid arching your lower back as you press overhead.

Common mistakes

  • Letting the working elbow drift forward or flare out, which shifts tension off the triceps and onto the shoulder.
  • Yanking the towel quickly instead of controlling the lower hand, which turns the rep into momentum rather than triceps work.
  • Arching the lower back to push the arm up, which strains the spine and cheats the range of motion.
  • Stopping short of full elbow extension, so the triceps never fully contract at the top.

Frequently asked questions

What muscles does the assisted standing triceps extension with a towel work?

It targets the triceps brachii, the muscle on the back of the upper arm. The towel and your lower arm provide the resistance and assistance as you extend the elbow overhead.

Is this exercise good for beginners?

Yes. Because you control the resistance with your own lower hand, you can make each rep as light or as challenging as you like, which makes it a beginner-friendly way to train the triceps without equipment.

How many sets and reps should I do?

For most lifters, 2–4 sets of 10–15 reps per arm works well. Since the load is self-controlled, focus on a full range of motion and a strong squeeze rather than chasing heavy resistance.

Where should I feel this exercise?

You should feel it in the triceps along the back of your working upper arm — a contraction as you straighten the elbow and a stretch as you lower. If you feel it mainly in the shoulder, keep the upper arm closer to your head.
