What is Interval Training?

Interval training is any run or workout where you alternate high intensity exercise and low intensity recovery or just rest. This method of training is great way for improving cardiovascular fitness, burning calories, and increasing metabolism.

Training Types Supported

• HIIT (High-Intensity Interval Training): Alternate between short bursts of intense exercise and brief recovery periods. Typically uses a 2:1 work to rest ratio (e.g. 40s work, 20s rest).
• Tabata: A specific form of HIIT consisting of 20 seconds of all out intensity followed by 10 seconds of rest, repeated for 8 rounds (4 minutes total).
• EMOM (Every Minute On the Minute): Perform a specific exercise at the start of every minute, then rest for the remainder of that minute before starting the next exercise.
• AMRAP (As Many Rounds As Possible): Complete as many rounds of a circuit as possible within a set time frame.
