Do you know what an EMOM is??
In case there is someone out there, like my husband, who does not know what an EMOM is I am going to try to explain. Because... my husband did the wrong workout today without me. He did the EMOM but he did not know what that was. He did one minute of each exercise every min for the duration! He said it was the hardest workout ever.
So, in this workout, when the first minute starts you will do 4 push-ups, 10 high knees, and 20 jumps during that minute. If that takes you a full minute then you will get a 10 second break and when the second minute starts you will do those 3 exercises again during that min etc. However, if you get those three exercises done in less than a minute then you get to use whatever time is left in that minute to rest before moving to the next set at the beginning of the next minute. Hope that helps.
