I was working out 3 times a week. then I started commuting and didn't want to stop working out. I decided I was going to ride my bike Monday through Friday and still work out Wednesday and once on the weekend. Come to find out I think it was a little too much because I became a bit ill. It's 12 miles round trip to work and 70% up hill one way. I'm 46 yrs old and think I need to change it up but not sure the best way to go about it. Looking to get some ideas from others who may commute as well as workout.
