Insane cage. Sets the standard without breaking the bank. So many holes you don't know what to do with yourself. I have actually lowered the pullup bar so I don't hit my head on the ceiling when doing pullups. It was easy to put together too and you don't need a second person for assembly, but it definitely helps. The 3x3 being the new standard now helps with all the attachments you can add to this (of which there are many!).

This rack is my first power rack, and I can safely say I will never need another rack. It's built solid, and I have no fear of any issues with the support it will give me when training. The only thing to mention is when choosing spotters to order make sure you consider spotter height, I have now ordered the pin and pipe spotters as well as the strap spotters I ordered with the rack as I got pinned under a swiss bar floor press due to the straps having too much slack for the movement at the max height the spotters could be set at for that movement. This isn't the fault of the rack or spotters in any design that's solely poor planning on my behalf with the movement I was doing and the general design if strap spotters and luckily I was able to free myself and as soon as I wriggled out I ordered the pin and pipe spotters. I have a number of rack attachments now for this rack and use it daily and couldn't be happier with the quality and versatility of the rack!

Absolutely solid rack. I bought the m4 230 x91 and its brilliant. I have bolted it down and it doesn't move a bit. Really impressed with the strength.

This is my 3rd Rack and by far the best. Heavy duty premium quality. I went for 230x109. I train solo so wanted to train within the rack for safety. Huge room with the 109 version. Easy to build. My rack was shipped to Ireland , delivered to my address over 3 days , 3 individual parcels. One main draw for me to the M4 was the range of attachments. The westside hole spacing is excellent for that perfect j cup height and the laser cut numbers are beautiful. I love ❤️ this rack especially the orange version. Well done Mirafit , ye nailed this product!

I wanted to update my garage gym, so I ordered the M4 plus some attachments. From ordering to delivery absolutely 1st class service. The rack was packed really well, never seen anything packed like this. The M4 was easy to put together, wow What a rack, heavy duty well made and paint work that stands out. I went for orange. It is an absolute beast! And is definitely built to last. There is so many add ons as well you really can have the ultimate set up depending on your needs. I've added the dip station, a land mine attachment and the utility platform ideal for box squat. I also got some resistance band pegs, I'll also be looking at adding the monolift attachment in the future. Well done mirafit what a perfect piece of kit what an investment

This is built to last and is in everyway what you'd expect to find in a proper, and well spec'd commercial gym. It's joy to use, and was easy to assemble. I'd definitely recommend bolting down, it will move otherwise.

This is a great rack,sturdy and built to last.
Not too bad to put together,the instructions look daunting but it is mainly just the same nuts and bolts repeated.
This will last me many years.
