4 Minutes of Training Could Save You an Hour

A recent study showed that spending more than an hour at constant speed and intensity doesn’t improve your body’s ability to generate energy. On the contrary – shorter, harder efforts do a lot more to increase energy production and improve endurance performance.

According to a study from the National Institute of Fitness and Sports in Tokyo in 1996, interval training of 20 seconds with a 10-second rest, repeated 8 times for a total of about 4 minutes of training, improved aerobic capacity by 14 percent, compared to 10 percent for an hour’s worth of training.

What does this mean? That four minutes of hard work can lead to better training than an hour’s. Good news for any athletes looking to improve performance, especially those juggling the time commitment of training with other needs like family and career!
