01 Sep The “John Boos M.A.S.S.” Equipment is Like No Other Strength Line

The “John Boos M.A.S.S.” equipment is like no other strength line. Developed by John Boos, in association with King Strength Mfg, it incorporates John’s decades of learning the benefits of strength training for all ages. While important for everyone, strength training is even more crucial as we advance to middle age and into older age. John and his clients use the M.A.S.S. items daily at his “Boos World” training facility in West Babylon, New York. You will hear John’s thoughts on training and equipment in the videos on the M.A.S.S. page. For proper function, training options and effectiveness, the M.A.S.S. equipment is outstanding in every detail.
