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.

    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.

    Great addition!

    This thing feels great! Knurling is passive but not a big deal. Gives a way better feel than bands. Great resistance curve and a perfect way to warm before lifts.

    I’d buy again if I ever needed to 🤙

    Hey Garrin,

    It's awesome to know it's become your go-to warm-up tool and delivering a better experience than traditional bands. Thanks for the feedback on the knurling too - we're always looking to dial in those details.

    Yours in strength,
    The B.o.S. Crew

    Very well made

    Love this thing. I don't have the money to spend on the high end chest expanders and the cheap ones from Amazon sucks. This one is solidly built, heavy, and feels very reliable. Chest expanders are a great addition to a home gym. Especially if you get a high quality one like this.

    Solid, heavy, sturdy, great piece of equipment! Did I mention...versatile?

    I am a fitness enthusiasts. I have purchased many pieces of exercise equipment over the years and this one will be used often. I thought that I had decent strength, but this machine has humbled me. I highly recommend it. Get it as soon as you can, there is a wait for it now, (should have bought more when it was in stock) and I anticipate it will be a huge seller. I think the price is fantastic for the quality. I have seen cheap plastic ones at almost the same price. (maybe I should be quiet about that) One more thing, the construction is top notch and it should last for years. I am going to purchase at least three more for friends and family. If I could have only one item to choose for my strength workouts, this would be it.
