Gains After Just 6 Workouts

Gains After Just 6 Workouts High Intensity Interval Training (HIIT) is a great way to quickly build up your exercise capacity. Some studies suggest that improvements can be realized after just 6 workouts. Research published in the Journal of Applied Physiology helps explain the mechanisms behind this rapid rate of improvement.

Sixteen inexperienced subjects performed six sets of 1-minute all out rides on a stationary bike with 75 seconds of low intensity between sets pedaling to recover. They did two of these workouts a week for a total of three weeks. Analysis showed an increase in skeletal muscle respiratory capacity due to an increase in muscle mitochondria.

True Strength Moment: Mitochondria produce energy in the form of adenosine triphosphate, more commonly known as ATP. This is the energy system your muscles rely on for short, intense bursts of power like sprinting and weight lifting. Increasing your training capacity is just the beginning, so keep going strong after that sixth HIIT workout.
