OVERVIEW
This cage is capable of handling serious work-outs. I'd feel comfortable using 300lbs of weight on it. I'm 6'1 and the proportions of the cage fit me just fine. It's sturdy & has a relatively small footprint. The best part of using a cage is that you can self-spot and, therefore, push yourself w/ less risk of injury.
If you add a 300lb weight set (Weider's rubber-coated is an incredible buy and will not rust), an adjustable bench (FID46 is good choice - sturdy & comes w/ leg extension, incline, decline) & dumbbells (adjustable take up less space, but Weider's rubber-coated plates can be used as makeshift dumbbells), you will have a very functional gym that goes beyond general fitness.
I looked at a couple of other cages, and BodySolid's Powerline is the best buy.
ASSEMBLY
The unit arrives in three large boxes. It's heavy (which is good) and surprisingly easy to assemble. All parts were included with my shipment and all parts fit as they should.
EXERCISES (after adding weights & a bench)
Everything you need to get in shape and build all parts of your body with the safety of self-spotting
CONS
No major complaint. The 2 lift-offs and 2 safety rods are painted. When slid through the cage holes, paint peels from them every time. Not a big deal, but they should've been left unpainted.
EXTRAS
10-year warranty, chin-up bar
The lat tower is an option, but I find chin-ups much more effective at building back muscle & symmetry. Plus I save money and space.
I'm 210lbs and this unit is able to support substantial weight on the lift-offs while I perform chin-ups. Though not professional-grade for power lifters who use over 400lbs, if you're still wondering if it's stable or sturdy enough for you to lift heavy weights, the answer is absolutely. This unit is hearty enough for you to get buffed. I'm pleased with my purchase.
