Monster Is What It Is...

What an absolute unit this rig is, seriously I cannot believe the quality and size of this thing... The guys that came to assemble it were professional and really nice guys who I spoke with quite a lot.

Kris Baychek
It Does It All

It does it all! Very pleased with the build quality and features. This piece of equipment anchors my personal training studio and allows me to program for clients with commercial gym memberships so they feel they have experience with movements under guidance of myself before executing my programs by themselves. Highly recommended for the home gym if you can afford it, you'll not needed a gym membership with this at home.

Force USA monster G20

Gym is excellent quality but instructions were poor and microscopic. For such an expensive and good quality product I would definitely suggest you look at this.
