Monster Pull-up Spheres

Rogue’s Monster Pull-Up Spheres are dynamic grip strength tools designed exclusively for use with our Monster Series Rigs and Racks. A new version of an accessory popularized by gymnasts, martial artists, and rock climbers for training and sustaining better hand strength, Monster Spheres are made from powder-coated 9-gauge steel and can be mounted to any 3” depth tube with 1” holes—specifically the XM-43 and XM-70 Monster crossmembers.

Monster Pull-Up Spheres are sold in sets of two, and are available in your choice of either a 3” or 5” diameter (beginners will want to start with the 3” option, as the 5” size poses a substantially greater challenge). Fully customizable, you can add just a single pair of Spheres to create a unique pull-up station or line-up a whole series to make your own obstacle course out of a Monster Rig.

Important: Monster Pull-Up Spheres are compatible ONLY with Rogue Monster Series Rigs and Racks. If you want to add Pull-Up Spheres to an Infinity or Monster Lite unit, see the options below.

Monster Pull-up Spheres is rated 4.5 out of 5 by 2.
Rated 5 out of 5 by from Legit. I recently added the 3" spheres to my RML-390F and couldn't be happier. I couldn't fit the monkey bar crossmember due to low ceilings so these were a great alternative. They add a great variation from the standard pull-up bar. You can also do neutral grip pull ups on these, so it makes them pretty versatile. The 3" is a great size (I am 5'7" with pretty average sized hands) to work on grip strength. My only slight 'issue' was I didn't know how tight to crank these down. There is a rubber spacer and the more you tighten the nut, the more the spacer 'crushes.' I just tightened each until they felt solid and ended up with 5 threads showing on each screw. Works for me. Oh and the quality is excellent.. perfect powder coating and solid hardware. Well done Rogue. Well done.

Rated 4 out of 5 by from Try the 3" spheres first... Having large hands, I immediately jumped to the 5" sphere -- in hindsight, given the different stresses on grip and wrist, I would recommend starting with the 3" model to build the requisite hand strength to fully utilize this piece of equipment. Build quality is first rate, though the bolt threads are showing signs of oxidation (my rig is outdoors); not a galvanized / treated piece of hardware (like the fasteners shipped with Rogue rig products); does not impact the functionality of the rig. I touched it up with Krylon / Rustoleum textured paint to soothe my OCD eyes.
