Spirit Fitness i-Strength
The i-Strength system utilizes electronically adaptive resistance to provide training methods – such as Pure, Eccentric, Isokinetic, and Elastic modes – that were previously limited to specialized equipment.

I highly recommend the B52 Pro. The smith bar and pulleys are smooth and the unit's build. You're more than comfortable lifting heavy weights on the machine.
The rower is excellent. Simple to use, but extremely effective and efficient for cardio and muscle workout. Fitness Exchange staff are extremely knowledgeable and helpful!
Bought the 65, 50 and 20lbs they are a great addition to my gym. (this is a incentivized review)
Great piece of equipment. Third one I’ve owned.
