Resistance Strong - Resistance Training Reinvented

Imitation is the sincerest form of flattery...

I am sure it is nicely made, but the design has limitations.

• Brushed stainless steel are sleek and easy to clean, but can make for a slippery surface. We use textured wood panels for better grip.
• The rollers along the long edge are likely to get in trouble at their 1000 lbs load rating.
• As far as I can tell, they use UHMWPE rollers on polished stainless steel pins as sleeve bearings. Smooth and quiet, but with a friction coefficient of 0.1 to 0.15 (source: Google) I would not claim "near zero friction". A friction coefficient of 0.1 means that you get about 10% more resistance on the concentric, and 10% less resistance on the eccentric. The actual numbers may vary depending on material and geometry. Ball bearings are more slippery than Goblin snot: Expect them to have at least one order of magnitude lower friction (friction coefficient of 0.001 to 0.005 according to Google search). A trade-off is that ball bearings can be a little more noisy. Eccentric resistance is valuable for hypertrophy, so why settle for a higher friction solution ?
• Their design does not support center pull for belt squats, or pinning the band in place for one arm rows.
• Looking at the demo video, the band is going slack at the bottom of the deadlift, as their foot plate does not allow shortening the band like the band box does. Resistance in the stretched position is good for hypertrophy...
• Their quoted price is $499. The total system cost including bar and bands is MUCH higher than for the band box including all accessories.
