All songs vary, but they can range anywhere from 3 minutes to 6 minutes. Probably 3 minutes and some seconds to 5 minutes and some seconds to be exact. I'm just rounding it off.
If I can. Otherwise, just what I can do, and will probably do the exercises that I couldn't do in the next song. In other words, I plan to do alternations. Jump up and down until I get tired and/or bored of it, and then switch to jumping jacks, (maybe 15) and then switch to toe touches, (maybe 15) and then switch to stationary running until I get tired and/or bored, and then switch to about 10 push-ups, and then switch to a few karate kicks that I know of. And then in the next song, I will try to shoot for 30 sit-ups, and then the next song, just do as many sit-ups as I can along with the other exercises. Something like that. I wish I owned something very spacious like a gym; then I would just run or jog around the building until the song stopped and rest in the next song. Unfortunately, I don't own anything spacious enough.
