The best portable workout.

The Resistance 90 portable resistance training system is a lightweight kit that you can take anywhere. You can set this up on any door using the Spine strap or the foam door anchor, and then you can do a full workout or key in on a specific muscle group.

Resistance 90 supplies you with a dual-band Slastix resistance band at your desired weight and color selection, a collapsible arm bar, and your choice of either a foam door anchor or a Spine Strap. The foam door anchor can be secured to any point of your doorframe, or the Spine Strap can be secured to your door and provide immediate access to seven possible anchor points from the top of your door to the bottom.

Resistance 90 adapts Stroops’ patented Slastix resistance band technology to create a product that is long-lasting, safe, and attractively designed. Slastix resistance bands are made to protect the tubing from outer abrasions that would otherwise weaken the band and hasten its breakdown. In addition, you’ll be kept safe from potential breakages as the safety sleeve restricts the band from wild snapbacks.

Resistance 90 is the future.

At the core of Stroops is our mission to change the game in the fitness industry around resistance band exercise. Too many people have become used to seeing their resistance bands as a replaceable and often breakable component of their exercise gear, and others know all too well what it’s like when a band breaks mid-stretch and becomes an immediate danger to them and others around them. These are symptoms of the conventional design of resistance bands, what we call “naked tubing.” It’s like driving a car without a seatbelt.

With Slastix resistance bands, we’ve solved this problem by designing a protective sleeve around the band. The safety sleeve serves a dual purpose to keep cuts, nicks, tears, and other abrasions from damaging and weakening your band, while it also protects you from getting hurt or injured by a broken band snapping back at you. The sleeve also maxes out at a safe length that stops the band from hyper-extension, one of the quickest ways for your band to break.

Limitless potential.

The Resistance 90 system can be used to work out every part of your body from shoulders to legs. The benefit of Resistance is it can either be taken on the go for freestyle exercise or set up with your Spine Strap or foam door anchor for an at-home workout session.

Using the dual handles on each band helps you isolate your muscles during reps while still exercising both sides of your body equally. For a different use, add the collapsible bar to each handle to enhance stability in your exercise.

  3. Chad Pittenger

    Amazing Product and My Clients are Loving it & alot of them do not like Weight training. I can train them anywhere!

  4. Lena G.

    What a great product, and very innovative design. In this day of home confinement gyms it can provide a well rounded workout, all in one compact package. I’ve been able to do most of the exercises I normally do with my gym’s cable cross machines. The door anchor allows me to easily install inside in a door jam, or bring it outside and strap it to a tree in the garden. The enclosed workout sheets are a handy bonus! I highly recommend.

  5. Devin C.
