Question: Can you do push up from the top bar?  Thank you.
Document: I broke my foot last month and wanted to continue with my workout regiment so I decided to purchase this Portable Pull-up & Push-up bar. When it arrived it was easy to assemble by simply matching the letters accordingly. Not heavy at all and one can easily close and slide under the bed, against the wall or place in the closet. You'll get a great workout. I recommend those who like to use their own weight as resistance to buy this equipment.
Good design, as I wanted something to use in my bedroom during the frigid winter months. Folds for easy storage under the bed. I need to do inverted rows, to balance out the push ups, which are made easier for my wrists, due to the floor handles. It is ideal for inverted rows. I am just under 6' and the bar is slightly out of palm reach, which is fine. I wear 34-35 length shirt sleeves, for reference.
I'm still working my way up to full push-ups!
I am a heavy guy that cant do pull ups but I can do push ups. This is perfect for building my back muscles.
The metal is very strong and can really hold weight very well. Max weight is about 300lbs if im correct but it can do more then that since i was trying it out with a weight vest close to a total of 320lb to 340lb. my only reason for not giving this workhorse a 5 star is cause i had to do some changes to it. As well one of the sides to do push up from is not even.
This is a very good piece of equipment, and of decent quality. We beat the heck out of it, too. We primarily use this as a part of a hing-impact fitness boot camp circuit. As such, it gets constant use, and from women who are just at 100 lbs to men who are mid to high 200's. It stores nicely and is easy to set up. We use it on top of fitness mats and it is pretty steady.
In ten minutes, I can do pull-ups, push-ups, and crunches/leg lifts, hitting all the major upper body muscle groups.If you're a body builder, this thing isn't for you. But if you want a good training aid to help you get into decent shape without breaking the bank, then this might be just the ticket.I'm about to start P90X and I think this will be really helpful with that.
I wanted something to supplement dumbbell back exercises without having to go to the gym and this tool is just the ticket! Made of sturdy metal bars and tubes, the unit can easily handle my weight and stays in place when I do pull-ups (I haven't attached the push-up handles). It folds for storage so I can hide it away when not in use. A very good bargain for the price.
The bar is very sturdy and was easy to put together too. It also provides a great forearm workout as well.
This is an excellent inverted pull-up bar. It's high enough that you can get a full arm extension. It's sturdy, easy to fold, and well-designed. I use mine on a rug-covered floor and have never had any problems with stability or slipping.
