Simple and beautiful Tabata Interval Timer (20 sec rest / 10 sec rest) for 1 Set (4 Reps) workout, full workout takes only 4 minutes. If you want a longer workout I also have an 8 Rep Tabata Timer on my channel.

If you want some fun activities for the iPad, or some help with computer issues have a look at my other YouTube channel at: [ Ссылка ]
