My wife and I took turns skipping. I skipped, then she skipped as I rested and so on. She skipped up to 1,000 and I skipped up to 1,300. I did not really feel spent. I think it was because of the long breaks I had between skipping sessions while my wife skipped. I decided to have a time limit next time, so that the rest intervals are limited. I was timing my wife’s skipping and it worked out to about 125 jumps per minute.

I set myself a target of 20 minutes within which to complete 1,500 jumps. I set the timer on my phone and started. Twice, I managed to do 200 jumps non-stop. When the 20 minutes were up, I had completed 1,340 skips. I could probably have met my target with shorter rest periods at the beginning. I was sweating and could feel that I had exerted some effort.

This time I managed 1,425 jumps within 20 minutes. I believe I can manage the intended 1,500.
