It does not matter Velofel if your pace is slow as long as you can go for increased distance without getting exhausted so easily. Biking. Biking is also a good way to train your heart to endure stress. In biking, your leg muscles and buttocks muscles are being worked out. The most important thing to focus in biking is how you train your heart to keep on working even under compromising circumstances. In biking, there are three types of tracks – plain, downhill, or uphill. You might want to gradually try out all three of them, starting from the downhill track then the plain track and finally, the uphill track. Remember not to build your Velofel stamina slowly.
