Since spring has came, we have a lot more energy for everyday activities. We are doing renovations in our apartments, decorating the garden, sometimes also going for a short trip to the mountain. But the most people begin to exercising. They're going to the gym, practicing Yoga, having pleasant fun on the tennis court. If you do not have to many time for any stuff like that, but you still want to get in shape, you could start to use a bicycle. But not regular one - you have to design your own bike!
