No need to ask for a spot ever again.The XPT Sport takes the same safe self-spotting mechanism as the Pro, but with a compact power rack that can fit in homes, corporate fitness facilities, and fitness clubs. By adding the two high/low pulley weight stacks (sold separately) you’re able to get almost every single station machine movement and free weight movement capabilities in one compact space saving, yet safe application. Perfect if your working out alone at home or in a group training environment to where now the trainer can give individual attention to each member of the group instead of just hovering over one area spotting. The trainer’s influence is amplified.
