I don’t see how you can coach swimming without StrechCordz!
– Bob Karl Head Coach, ASCA Certified Level 4

I endured year of masters swimming within the Army doing more distance, pushing harder, striving to be aerobic, technique tweeking, etc. After that capped-out, more of the same did nothing. I started using the drag chutes from strech cordz. I started with one small (8-inch) , grew to two 8-inch chutes, grew to two 12-inch, and I’m headed for a 16-inch chute. The chutes have been more productive at increasing immediate strength, arm stamina, terminal strength, and total endurance more than any other tool I’ve tried. Positive results are defined. I swim with someone else who has used the chute infrequently, yet she too has gained positive results despite less than optimal usage.

Our high school team has used your TurfCordz Safety Corded Tubing for several years now and I wanted to write to express my admiration for the quality materials and craftsmanship of your products. The kids really get into the drills and as a coach, I really appreciate that. Keep up the good work!

Thanks for many years of a great product! I first used StrechCordz in 1991 when I was a swimmer in high school. I ordered a Modular Set to use in the off season and I have continued use your products faithfully ever since. I want to thank you for not only a great product, but also for the part StrechCordz played in all the great memories from the many years I spent swimming. Those memories and lessons of dedication, hard work, camaraderie, friendship and personal ethics serve me well today. Thank you.

You can recognize me by my ape size neck when I walk down Michigan Avenue. As a football player, I’ve had my share of injuries, but when I injured my neck I asked my chiropractor how she adjusted football player’s huge necks. She teased me saying we had no neck, and then started me with MediCordz for rehab. I was back on the field before I knew it. Resistance therapy saved me from painful neck issues in my later years. After an auto wreck some years ago, I used your MediCordz Headset Kit to rehab and have continued to use it since then! Thanks for making great gear. You may quote me. I have shared your technology with others who have similar needs to mine.
