    Fun instability training for everyone

    Who says instability training has to be intimidating?

    Our latest (and smallest) addition, The Cube 7, is 50% lighter than the FX Boba 13–making it the perfect tool to have fun working out. Although primarily designed for seniors and beginner lifters, The Cube 7 is also your ally to hit your body-weight training goals.

    Challenge yourself to do more reps and push-ups anywhere, anytime without burning yourself out. Made with superior damage-resistant neoprene, you can lift, squat, press, and just have a good time, without worrying about leakages and tears. Start your instability training journey with The Cube 7 now.
