“I get so sweaty doing this workout; I love it! I usually do this in the gym, so I'm naming the machines I use, but of course most could be done with just a pair of dumbbells if that's what you've got. I do 30 seconds at each spot and I use an interval timer (app on my phone) so I don't have to keep looking at my watch. I move to the next thing every time it dings. After the second time through I get a 1-minute ‘break’ and grab some water. Do circuit 4 times and follow up with a 3-4 mile run. The below example focuses on triceps and biceps, but you can customize it to any muscle groups you want."
