Document: Mini Leg PressThis machine is biomechanically unsound. I purchased it for my son BUT, in order to get the correct angle to press on the platform, you have to lift your buttocks completely off the seat. I had to return the machine at my own expense and purchased another model.THERE ARE 2 PROBLEMS WITH THIS MACHINE:1. THE BACK SUPPORT IS TOO VERTICAL AND IT CANNOT LAY BACK ANY MORE BECAUSE OF A BUILT IN STOP.2.
we have a limit amount of space. This &#34;Mini&#34; leg press works great for us. Although it says &#34;mini&#34; it IS a good size and DOES work well for our needs.
When the machine arrived, it was missing all the hardware required to assemble. Other than that it meet my expectations.
There were bolts missing. The instructions were hard to read copies. For the price I would have expected well done instructions. Once they sent me the missing bolts I was able to assemble it. It works good.
The machine works fine. I might prefer to incline the back support a little more, but this could be done by removing the set screw. At first my feet tended to slip downward so I braced them against the two support bars. With use this problem disappeared. It eliminates the squat exercise with hand weights that I found exhausting, but do not experience this with the Mini Leg Press. I recommend this to anyone who seriously needs or wants to keep his or her legs in shape.
The customer service was fantastic! The leg press is small enough to fit in the space I had, and works great! !
THIS IS A WONDERFUL LEG PRESS!!!! IT WAS VERY EASY TO ASSEMBLE AND IS MADE OF GREAT QUALITY PARTS!!! I'M VERY HAPPY WITH THIS!! !
Regardless, it was not until I actually sat in the seat and got in the machine that I figured out why it it was so difficult. Notice that any other photo of any leg press machine on the internet shows the seat sitting directly on AND at the level of the glide track. I do not recommend this particular machine despite the low cost.Joseph Fernandez, M.D., FACSSports Medicine SpecialistChairman, Department of Orthopedic Surgery Baptist Hospital Miami, FLClinical Assistant Professor University of Miami Department of Orthopedic Surgery
One should start slowly with minimal weight then gradually increase.
Equipment arrived in three boxes on a pallet. The bottom box was damaged and wet, when the delivery man unloaded the pallet off of the truck two items fell out of the bottom of the box. The driver noted the damage and the possibility of missing parts. There were several small parts missing, along with the hardware. The emails I sent were answered promptly and the items were sent out right away! Unfortunately, FedEx damaged the box of parts and I was missing one of the mailed parts!
