Make your own fitness club that is open only for the best sportsmen!
Upgrade not only your muscles, but also work on your fitness club, add all new exercise machines, and clients will be happy to come to practice only to your club. You can offer them personal training, help with the meeting of standards, and even with preparation for the championships. And if one fitness club is not enough for you, you can always build another one with the better starting conditions!
You will have to find a personal approach to each of them as one never knows who is in front of you: a novice athlete, an experienced fitness instructor, or just someone who came here just to have fun. But it makes it even more interesting, you can offer to make a training program, help with making exercises correctly.
