During last decade Jan Marvan, former professional cyclist and the team of experts (ice hockey players from NHL, professional athletes, trainers, physiotherapists and material engineers) came up with the first training tool called COBRA, a long heavy elastic battle rope with countless applications and exercises. Training with heavy elastic power rope was one of the best and most beneficial training methods to prepare the body and all muscles for a hard season of professional athletes.

The result was a perfect traning tool, easy to transport to training camps even by airplane.

This became immediate everyday training tool of dozens professional athletes, army and sport clubs. After years in heavy duty, many training units and continuous tests by strong NHL ice hockey players, the Cobra tool proved that it is the most durable training “partner” for everybody. From professional field to fitness people.

A few words from Jan

I came into fitness industry around year 2000. I started as a presenter at big shows for Johnny G and later for his Kranking program. At the training camp in USA I got an idea for new training tool and I had a pretty clear vision how to develop training system for it. I started from the bottom with nothing, just me and my idea. I bet everything on it and focused solely on making it better.

What followed was many years of testing, developing, playing with different versions… Then I met few good coaches and couple of guys from NHL and I put them through several training tests. They were ecstatic and full of enthusiasm for my new training tool. This was the first success of the Cobra rope and big milestone for me after those years.

Now we are present in 20 countries around the world, in professional sports and also in fitness market. I’m really proud of GUN-eX and the team of friends I made all around the world.
