Get a bike, you will thank me years later. I ride 25-30 miles daily, best thing I've ever done, easy on the body with less strain. When I'm done, it's not like I feel "oh sh*t" what a workout.

I use to run 2-5 miles daily, had two knee surgeries from football, was told years back I would have to have knee replacement. Was getting the "rooster shot" once maybe twice year. No longer do, wish I would have done this years back.
