Testimonials
A year ago I was forbidden to keep up my mountain climbing hobby. Heart pains occurred, and I got the diagnosis of myocardial ischemia, stenocardia. As a result I was recommended to be operated on. Instead of operation I started exercising with the Frolov's training device under physicians' observation. This summer after exercising on the training device for 9 months and complete medical check-up I resumed active training at the mountaineering club.
