Jason thought this three part circuit workout that he does with his clients would be fun for us too. It will get your heart rate up and strengthen your body at the same time. That is what I call a win-win workout. It is full of mutli-joint exercises that work more than one muscle group at a time and the more muscle you use in a movement the more oxygen you need for those working muscles.
Keep track of your rest times and weights, so you can decrease the rest time and increase the weights from week to week. If you are new to weight training, Jason recommends starting with no weights and 1 min rest between sets. On the flip side, decrease the rest time if it feels too easy, but remember you have a lot to do so don't get ahead of yourself.
