Make It Mine

When you buy this machine you can do more than just the typical back extension and and crunch/sit-ups.  This Hyper Extension Machine by Yukon is easily adjustable to accommodate for the Glute/Ham Developer exercise.  The ankle pads and footplate adjust up & down and forward & backward for variable distance and height options.  The rounded pelvic pad is also necessary for this exercise.  Remember, you save money on higher-quality Weight Training machines by shipping them directly to your house!

So how does the glute/ham developer exercise work?

Lock your feet on footplate and ankle pads. Rest your hips on the pelvic pad and stretch down.  Now, either put hands on the chest or behind the neck.  Then pull back up using the entire back, glutes and hamstrings to bring your body back like a normal hyperextension, but then continue on up by bending your knees while pulling your heels to your glutes.  Notice how the knees bend. It's like a prone reverse leg curl, except your whole body is used as the weight instead of a pulley and weight plate.

I decided to get the 45/90 degree roman chair by Bodycraft.

"After spending time researching the excellent information on your site... I chose the 45/90. I liked the idea of being able to progress from the easier (45 degree) workout angle to the more difficult (90 degree). I found the thigh pad to be extremely comfortable, like I read in Dr. Knudsen's review. I was worried about putting it all together, but the instructions were easy to follow. It only took me about 30 minutes to put together."

Wendy S. - Tennessee

After careful consideration I chose to buy from your site.

"I noticed that your prices were just as low or lower for the Powertec Dual Hyperextension than all the other web sites, but your information was so much better that I wanted to give you my business.

I felt safer knowing that BackTrainer.com has been around since 1999 and that I could trust that your company would delivery the goods in a timely manner. I was very pleased with your service and I can tell that these roman chair hyperextension exercises are going to build my core muscles.

I can already see a difference... my back and abs are getting ripped already!"

Sam F. - Oklahoma

""I watched your bonus video - it helped me to understand how to use my equipment better. Seeing that you have the lowest price, too... it was a "no brainer" to buy from the backtrainer.com web site. Thanks for all the great information and the quick customer service. I was glad to receive the emails that told me when my roman chair would arrive!"
