Tale from an Asthmatic point of view


First, I want to say that I have Asthma. Some workouts for me are too long and I can't keep up the pace. I started this workout about one month ago and it took me about 20 minutes to get one workout done. I can now do this workout in 7 minutes or less, depending on the day. I have introduced this workout to people that I know and you will not believe the response. Some people think I am crazy when I tell them about the "4 minute" workout. My goal is to tell people about a workout that can be done in as little as 4 minutes and not become such a chore to do because they don't have the time. We all have 4 minutes. I encourage everyone that it may take some a little longer to do, but that is okay. Finishing the workout and not having to count anything, is the best part. Thank you for this app. I truly enjoy it and I am down 5 pounds since starting this amazing workout.

Can increase intensity


I've looked at lots of tabata apps and a significant advantage of this one is that the exercises make it hard to plateau. Once you are doing a given number of one exercise with good form you can always add more repetitions to keep yourself in "full-out" mode for every workout. Plus the 4 minutes definitely keeps me committed. I've picked up and dropped other workouts within a few months. I'm still going strong with this one after a year. I've noticed results, too. When I am doing this workout 4-5 days a week I have much more endurance than when I'm not.

Love this app.


This workout is great! After the 4 minutes, I feel energized and refreshed. This feeling lasts throughout the day and I notice the pounds falling off when I step on the scale. I love that there is a weight tracker that allows you to keep up with weight lost/gain.
