Boxers, in particular, have a lot to benefit from internal training, especially when gradually increasing capacity for sets. Contrary to popular belief, Boxing Science shares that boxing isn’t an endurance sport but a repeated high-intensity one. Because of this, boxers must train to build a solid aerobic capacity.
Science Direct defines aerobic capacity or VO2 max as “the maximum amount of oxygen that a subject can use per unit of time and body weight.” To gradually increase VO2 capacity, a 2013 National Library of Medicine study claims that interval training, wherein you alternate short periods of high-intensity activities with rest, can do the job.
Interval Timer lets you customize your timer with sets, countdown times, low/high interval times, and rest times. Aside from this, it also has built-in features for things like playlists, sound volume, and timer sounds. One of the unique things about Interval Timer is that it integrates visual cues, such as color changes and titles, so if you workout in a crowded gym or have trouble hearing in general, these visual cues can help you stay on track.
Interval Timer is available for free on iOS and Android. With some users claiming that the ads can significantly affect your experience, an extra $9.99 for its annual premium plan can be worth it. Aside from removing ads, the Interval Timer’s paid tier also lets you integrate the timer with your Apple Watch, share routines, and even access templates for different kinds of workouts.
