Work your way up.

I was somewhat skeptical buying this product. Maybe it would be too hard for me. Maybe it would be flimsy and break within a matter of days. However, I decided to "put myself out there" and buy it.

To my pleasure, I found that they were incredibly durable. It comes with 3 stretchy/flexible cables, and you have the option to connect one, two, or all three on the handles.

When I opened the package, I tried connecting all three that it came with. I'm not very muscular, and thus, it was too hard for me. I brought the setting down to two cables, but it was still too hard. I started getting worried that these cables were too tough for me. When I switched to only one cable, and found it was just the right setting. After using it for about 3-weeks (2-5 times per week), I finally changed two cables. I found it to be easier than when I first got the package. I had been using this along with the Lifeline Power Up Chin Ups. This obviously was a sign that I was getting more muscular. I recommend that you start each workout with the lowest cord in order to calibrate your body/muscles, and then work your way up, so that you don't put sudden strain on yourself.

Also, the wider apart you hold your legs, the harder it becomes to pull the cables up. This also adds another level of difficulty that you can factor in when you're ready. I haven't yet reached the 3-cord setting, so it also definitely includes lasting "replay" value.

It also includes a strap that you can wedge into your door, face your back towards the door, and then pull forward to increase chest workout.

Overall, I would definitely recommend buying these (along with the Power Up Chin Ups). - Mark, California
