Build your back, bis, tris, and chest with this bodybuilding classic!

Product Features

  • Build Lean Muscle

    So, you're looking for that natural, wiry look like you can definitely push the weights, but still have energy to go a few rounds in the ring. This bodybuilding classic is a TKO for lean, defined muscles that pop in all the right places

  • Highly Versatile

    Don't let the name fool you: it comes from ye olden bodybuilding days. Target your back, triceps, and biceps with rows, curls, flyes, and even more when you anchor it to a fixed point or use two for bilateral work (#upsell).

  • Beginner & Pro Friendly

    With 7 adjustable springs on carabiners, you can remove and adjust the tension to suit your experience and goals. Beginners can remove springs for less tension and add them back and play this bad boy like a muscle-building accordion (Lederhosen optional).

Product Details

Don't let the name fool you: this bodybuilding classic targets the back, triceps, biceps, and more.

It's been a staple in bodybuilding for over a century for its effectiveness and versatility in building lean, defined muscle with that wiry, natural look.

Built for progression, this steel contraption has 7 springs with carabiner attachments, so you can remove or double up springs, adjusting the tension to suit your goals and experience level. When fully stretched, each spring provides 20lbs of resistance.

Beginners and pros alike can use this for curls, flyes, and rows or attach to a fixed point for presses. Grab two for even more versatility (shameless upsell!)

The chest expander offers consistent tension throughout the movement regardless of how many springs are attached, making it optimal over bands for bodybuilding.

The design hasn't changed much over the past century because it hasn't needed to, but we've thrown on rotating handles and knurling for that cherry on top of a swole sundae.

Watch your arm hair, though—and if you see Kaevon walking around looking smoother than a baby porpoise, mind your business.

IMPORTANT: Use a minimum of two springs on opposing ends of the handles to avoid over-stretching them. The warranty on the springs is 3 months, as they are considered a perishable item.

    High Quality, Great Value!!

    This was really good quality. I have some cheaper CE's and this BOS one is drastically better, for a very reasonable price. CE's are a great addition to any home gym, I'm glad BOS decided to start making them.

    Thanks for the fantastic review, Allison! We're stoked to hear that the Chest Expander is bringing that Bronze Era vibe to your modern training — that's exactly the kind of old-school meets new-school approach we love. It's awesome that you're seeing those deltoid gains and that half-inch increase in upper back thickness after just a month — that's some serious progress!

    Yours in strength,

    Chest Expander

    Hands down best Chest Expander on the market. There is only one that compares and it’s 4 times the price. Plus Bells of steel customer service is top notch.
