Železná koule

At Železná koule, we make people who don't exercise into people who do. We'll work out with you at Comic-Con! Come join us to touch the balls, enjoy the loud clanging of the iron, and measure your strength against others!
Every muscular hero has to take off his costume, throw on his sweatpants and go work out sometime. Luckily, all you have to do is download our mobile app and start working out anywhere, anytime and never do it stupid again!
Online coaching that has the balls is a gym right in your pocket! It includes several workout programs divided by difficulty and available equipment, detailed instructional videos, and a bunch of healthy recipes for delicious meals that even Kryten on Red Dwarf wouldn't be ashamed to serve.
