Select the number of exercises per round, rounds to repeat, rest and work time, and which exercise types you want to filter out.
You will try to perform one exercise for the duration of the work interval followed by a rest period. Then continue with the next exercise and repeat all of them each round.
Using your options, random exercises are drawn from the collection. Review and redraw if you need to. Update filters in the previous steps if there are exercises you can not perform.
Click "Start" and go for it!
Take breaks if you need to but try to only rest during the rest period.
