About this item

  • 2 in 1 Upper Body Training Machine: Perform back extensions and abdominal crunches from the same seated position. The rotary flywheel mechanism allows for complete control over your starting position. Replaced the installation of the limiters, a simple plug can be completed between the back extension and AB crunch mode conversion. Designed to save space and money by combining two commonly separate machines, into one compact, multi-function machine.
  • Perfect Bottom Support: This AB back machine has 8 adjustable positions of foot restraints. Adjustable distance range: 31.4‘’- 36.3‘’. You can choose the right length for your training. Foot restraints help anchor the user into place for better isolation and contraction of the posterior and anterior cores. The weight selector pin and stack are conveniently located for quick weight changes. Users can focus more selectively on target muscles, building core abdominal strength and back muscles
  • Adequate Back Support: The 2 inch padded cushion is made with a high quality leatherette surface that is easy to clean while guaranteeing comfort during your workout. The seat height also has five adjustable options, with an adjustable height range of 20.8''-24.7'', so don't worry about height being a limitation to your use of this upper body training equipment.
  • Full Range Adjustable: Rotary flywheel mechanism and pop pin design allow for easy adjustment. 27 selectable holes that enable you to achieve over 180 degrees of adjustment. It allows for complete control over your starting position.
  • Sculpt Core Muscles: The core acts as the center of your body and helps you utilize every other part of your body to maximum efficiency. Building strong abs can mean reduced back pain, higher quality posture, functional strength, increase in sports performance and better all-around balance. Ab machines can help fill the gap between bodyweight core training and a core hardened by progressive overload.

Very heavy duty

I received the machine this afternoon. The box was extremely damaged, luckily the packaging was enough to protect most of the unit, minus some scratches in the metal. Not ideal, but it is exercise equipment, I can live with it. This is the fourth heavy exercise Item I have purchased from Amazon, delivered by Fed-Ex. Please use a different carrier, Fed-Ex just destroys heavy boxes, and damages product.For the product. The machine seems well made and mostly heavy enough. I am only 5'7", @250 lbs. and with the seat at its lowest setting, and the legs at the farthest setting, the padded bar sits a little too low on my chest/back. I can use the machine "effectively", but it would be better if the bar was about 2-3 inches higher up, or with some adjustability for different body types, or a seat that drops further down. Maybe sell an alternate bar for adjustments? But so far it seems ok. Will update review after some use.

Love the machine, but you have to be very careful about the metal rod staying in the wheel

I love the compact machine idea.. but this is lacking in many areas... It's not for shirt people (I'm 5 ft) I can't even adjust it to my height for comfort.. the piece that holds the weight plates comes away from the base and I'm constantly pushing it in.. the angle of the seat is ridiculous so I'm basically standing up trying to use this machine and it's doing nothing but tweaking my back out when it's supposed to work my back out. If it wasn't such a bitch to put together die to lack of descriptive instructions, I'd return it for a new machine.. now I'm have to spend more money to try to make this work ..

I always enjoyed the back extension machine at the gym and this piece of equipment does a good job replicating it. It was an added bonus that the ab motion was just as good. Great machine

WELL MADE, STURDY AND WILL DO THE JOB. HOWEVER MY ONE RECOMMENDATION IS TO PLACE NUMBERS ON THE ACTUAL PARTS SO THAT IT BECOMES EASIER TO ASSEMBLE AND LESS TIME CONSUMING. OTHERWISE A VERY GOOD MACHINE.
