Finally have a new workout routine after moving and losing my city. 15 minute bike ride on hills to a gated community playground, arm work and push-ups, ride back. It sounds so simple, but it's awesome and very taxing. Takes about 45 minutes. I'm not going to try categorizing it. It's my exercise. I can control the intensity easily. I'm going to do it every other day on my days off weather/family/other BS permitting.
