i do about 20 minutes of elliptical a day, 6 days a week. sometimes up to 40 mins, other times i'll do a 15 minute high-intensity sprint... but it's all elliptical, all the time for me. wanting to save my knees is the main driver, my family has a history of bad knees and knee replacements. sometimes bike a few miles with the kids on the weekend, dunno if that counts.
might need to get back into pushups, sit-ups, flailing weights, etc.
