 Frank,  the "rubber band gym" in my basement is working great, we love it.  After following your instructions for a two week period.  Justins, 5'4" 150# 6th grader,  vertical jump increased 2".  Mine?  3".  We did squats on Monday, Wednesday and Friday for two consecutive weeks.  We tested  prior to the routine and the Wednesday of  the third week.  Worth the effort.  We also used the wall unit for resisted running, shuffle and some of the many other exercises that can be down.. Great product, great price.  Thanks..  Oh, by the way, installation was pretty easy.

Dear Frank,

I just wanted to drop you a quick note thanking you for the advice and assistance you gave me on my twisted ankle.  I twisted my ankle both inversion and eversion rolling over second base in a softball game 3 weeks ago.  Had x-rays less than 1 hour after injury.  No breaks, but given crutches and the old stand by info, Rest, Ice Compression Elevation, Motrin x 3 day.  The basic standard stuff.  Well you know me and my type A personality I was off the crutches in 3 days and trying to walk and move like athletes want to do.  I might not be 18 again but I won't let them see me sweat that's for sure.  Well I was doing physical therapy for several weeks and doing the ice and Motrin.  The no running for 3 weeks was killing me up until last week when I met with you and you placed the traction on the injury.  To make a long story short I just wished I would have hooked up with you and jump stretch 3 weeks earlier.  My pain is almost totally gone and I ran my first 5 K race since the injury just last Thursday.  The doctors told me no running for at least 6 weeks.  I wish some of these doc's would take a harder look at jump stretch and start thinking "out of the box".

Thanks again for your help and stay in touch.

 Above is P.K. using two mini Flex Bands and a average (green) FlexBand in the 'self' traction method of the ankle traction procedure on how to rehab a sprained ankle.  In most cases the swelling is gone and the injured it up and walking with in a half hour.  The procedure takes a little more work if the ankle has been immobilized and treated with the "RICE" method.  The picture was taken at Marine Corps Base, Camp Allen, Norfolk, Va. in May of 2004.  The MCCS organization, (Donna Overholt and Michael Corrie) invited me to attend the MCCS Health Fair to demonstrate the Jump Stretch Flex Band.  This was the 2nd Health Fair I had been invited to attend with other vendors and health related organizations.  Thanks Donna and Michael.

Chatted last night with my Test Lab buddies about the bands test:
Interesting stuff:

They cut several sections of each size, clamped each end and tested by stretching the section to 2x the sample length every second. Although their counting software screwed up they said that the number of cycles equaled 86,400/day (1 cycle per second). They tested for 58 days or 5 million cycles.

The largest bands retained their heat (80 degrees F) and got hyper-elastic after just a few hours. Apparently, they could not dissipate their heat well. They topped out at 18% increase in the ease of stretch. Their cold (40 degrees F) response topped out at 5%. Although they showed their cracks sooner than the smaller bands, they never failed as long as they were not stretched against their longitudinal axis (tearing motion).
The larger the bands the less forgiving of heat and cold. Probably because of a combination of the surface area and the mass of the larger bands. They conclude that the difference between the inner temperature and the outer temperature creates and inherent coefficient of expansion issue that makes the overall mass less stable at the molecular level. The larger the mass the greater the differential.

Unless the bands were stretched well beyond 2x, they seem to be very resilient. Both engineers say that the compound is good to superior in its consistency. Very few flaws that were problematic… some “bubbles” under microscope looked more serious than they were.

They had to harass the bands to get them to fail. Extreme cold combined with a “tearing stretch” were the only combination of acts that caused problems.
Their advice: Don’t pinch the bands in a cold environment. The bands “remember” and tend to weaken if chilled repeatedly. They can’t really say how much abuse the bands will take… but they both said that they would feel comfortable using them (if they weren’t such nerds). <= They laugh at themselves about being techno-nerds. Their only exercise is flipping steaks and drinking beer.

(What the hell does that make me?) Don’t answer.
Hope this helps you guys present your product’s features with more science.
