Description

Most chest and arm trainers let you down the moment you push past beginner resistance — springs snap, grips dig into your forearms, and the resistance feels uneven. The LifePro ShredForce is built differently. Its advanced hydraulic system delivers smooth, consistent load across ten resistance levels from 22 to 440 lb, so whether you're warming up or going all out, you feel every rep working. Use it for chest workout at the front, shoulder raises overhead, or back exercises behind you — it's a true chest and arm trainer that targets your full upper body in a single session. The carbon steel frame handles serious training sessions without flex or fatigue, while the PU rubber handles protect your grip so forearm pain doesn't cut your workout short. At just 5.06 lb and folding flat, the ShredForce travels anywhere — home, hotel, office. The built-in repetition counter keeps your training honest without needing a phone or app. Start at 22 lb if you're returning to training, or load up toward 440 lb if you're ready for a real challenge. Ten resistance levels mean this adjustable resistance trainer grows with your strength — you won't outgrow it in three months. This is upper body trainer equipment built around carbon steel construction for sessions that demand more.

  • Great workout tool!
Color: Gray
I get a great upper body workout with this! You can set the resistance up to 440 lbs. You have a great range to work with. You can really see the results. And it's so portable and easy to use. A great buy. I'm very happy with this!

  • Nice resistance and easy to use.
Color: Gray
I’ve been using this machine for about 2 weeks. I love the resistance adjustment and the quality seems to be pretty good. It’s easy to use and easy to store. I do wish the locking piece was built into the machine because I have to hunt for it when I’m done with it. Sometimes I just leave it open and lay it beside my bed. I love this machine so far. ... show more

  • Easy way to get back in shape again.
Color: Gray
This is a great device for toning muscles. I am 74 and my chest and arms have started to shrink due to lack of any exercise. This device has made it possible for me to start toning again. It is well constructed with adjustable resistance. I use it every day, sometimes twice a day. In the few days I have been using it, I can already feel a difference. Presently I am on Level 4 but should be moving up another level soon. I am very happy I got this and recommend it to anyone else that needs a convenient way to get their daily exercise. ... show more

  • Great overall.
Color: Gray
Great overall product. It’s easy to use, easy to store. The counter is a plus and definitely an upgrade. I had another brand in the past which was a bit more pricy but, this one checks all of the boxes for the price, you definitely get a bang for your buck. It’s strong durable and I enjoy using it everyday. It even comes with a booklet that features different exercises. I’ve taken it to work and introduced some of my friends and colleagues to it and they have now purchased one. It’s worth every penny. ... show more

  • Good quality and sturdy
Color: Gray
Bought this for a Christmas gift foe my uncle who has down syndrome and competes in special Olympics. The tension is good, there are 20 levels and he was able to start on level 4, you can invert to work different sets of arm muscles. This one comes with a counter thst you can reset which is an extra bonus. Sturdy and appears to be well made. We had a contest at Christmas to see how high we could go. Ages ranged from 83 to 19, most could make it to 10 with only one 20-yr old able to make it to 20. The only concern is it comes with a plastic hook to hold the arms together when not in use; however, a slight touch or grabbing it in the wrong place sends the hook sailing and the arms fly back open with a quick force. We just elected to leave it open for his safety. ... show more
