NOTICE: Because of the very high demand there can be an extended waiting time of 4 - 6 weeks. I ask for your understanding.
Many people has asked me for a high quality heavy duty chest expander – here it is:
This expander is unlike other expanders completely made from steel. The weight of the expander is 3 kg (6.6 lbs) and and you can feel the quality of the product once you hold it in your hand.
The handles are knurled for a secure grip and the handle diameter is 30 mm. When you pull the expander in front of your chest, the handles will spin so that you can concentrate 100 % on the target muscles. The expander can hold up to 7 springs which is more than enough even for very strong people.
The springs are made of stainless steel and the handles are chromium plated.
This product targets the upper back muscles and the rear delts.
Regular expander training can be used as injury prevention for the shoulders because you train the rear delts which are often under developed in most people.

- Graham Temple, 02/05/2026Using my expander over 2 years now and it's a great piece of equipment. Use it for your standard upper back expander exercises, also great for triceps and biceps. Couldn't recommend one enough. Solid craftsmanship and worth the money. About to upgrade with some stronger springs. and biceps. Couldn't recommend one enough.

People back in the 1900s got absolutely yoked with these, so a person in 2025 can also get absolutely yoked with these, they are very effective. 1900s got absolutely yoked with these, so a person in 2025 can also get absolutely yoked with these, they are very effective.

If you push hard enough the DOMS are unmatched in the upper back region. Completely overshadows any rear delt fly machine of any sort. Hope to be strong enough for the super spring version one day! Thank you Robert. back region. Completely overshadows any rear delt fly machine of any sort. Hope to be strong enough for the super spring version one day! Thank you Robert.
