Yes it is. Intervals are the latest hit in every sport. Although there were people who claimed that this kind of training can produce very good results during the 50s and 60s, it is for the last 5 years or so that they have got into the spotlight. Intervals are really great tool to improve your time, energy, stamina, endurance. Depending on your goal and distance you can utilize specific intervals. So go ahead and use them. You won’t regret it.
