Question: Are leg curls possible?
Document: If you are over 6' tall (as I am), you will have to compromise your form for leg extensions.The seated arm curl simply does not work. The resistance is from the wrong angle for a proper curl. You can overcome this by standing (facing the machine) to do arm curls.
With a little TLC and nice controlled movements this machine will last years and years and give me a full workout. A few miscellaneous other pieces of equipment and I can have a full gym in a 10 x 12 bedroom.Great buy. I recommend so much that I bought at Walmart and am rating it here. Good luck!
Use the second on the bars that hold the weights.Ok so it's not a really heavy machine but I like that it controls the movement in the bench but doesn't over control it. You will use stabilizing muscles just like with free weights but not to the extreme. I am 220 lbs and can bench the stack with minimal strain so if you are a hard core weight pushing junkie like I was when I was 20 go get a stack of Olympic Weight and don't complain that it isn't heavy enough.
They are arranged in the order you need them. The whole assembly process is well thought out. There are a couple of assembly steps that require some dexterity. None of it involves heavy lifting. The gym is a complex machine, but if you follow the instructions in order, you will have no trouble.Quality:The gym is solid and the connections are strong. Most home gym equipment is weak in the connections - where they quickly come loose and rattle. This one is well designed.
The gym arrived and the pieces all were identified by the instructions accurately. Assembly went great with no issues. Very nice product. Highly recommended.
The guide bars for the weights are not very smooth. The pulleys are as-cast, not precision. If you are looking for commercial gym quality - you will be disappointed. For the price, it is quite good.Use:I tested the resistance of the machine.
Pros:Well-madeEasy to assemble (considering how complex a machine it is)Very good instructionsMore resistance available than you would expect with a small weight stack (except Lat Pull bar).Very compact.Cons:It is not terrifically smooth, if you go too fast, the moving pulleys can hit bars and covers.Ergonomics could be better (seat is not adjustable, lat-pull bar doesn't clear the bench press levers by much, etc.
Other than that complaint, it does what it is supposed to do, quite well, and to my satisfaction.Follow the assembly instructions carefully, they are good. I made a mistake early by using the wrong bolts on the very first part of the assembly, and had to change them out later, it was not fun. Piecing together the frame on my own required some dexterity for a 70 year old man.
It took me about 8 hours by myself to put it together. If you are 6' or taller, this is not the machine for you. I would have preferred if the height of the machine was just two or three inches more, then the pull down exercise would be better (I am 6" tall).
It is easy to open the boxes and carry the parts up or down stairs before assembly. Once assembled it will be difficult to move. Fasteners are metric. Most hex-head bolts are 13 mm and 16 mm. The 16 mm size doesn't come in most socket sets (they have 15 mm and 17 mm skipping the 16 mm size). The two required sizes of Allen wrench are provided in the kit. The instructions are quite good.
Answer: yes
