I agree with tulip....make time to exercise, but don't make it too restrictive or regimented at first. Make it fun!
When I started cycling again a few years ago, I just started by going around the block, then around my neighbourhood, and before long, around the city and far beyond. Some rides I'll do a familiar route, but faster than before. Other rides I'll do a familiar route but extend it longer by discovering new roads/paths/trails to explore. Sometimes, I just strike out in a totally new direction and see what happens.
The important thing is to get moving, and keep moving. How often is up to your interests and your body/fitness level. Set goals, but keep them modest and realistic....then as your fitness level increases, build on them. Enjoy the good days, and don't sweat the off days that we all have. Have fun!
All vintage, all the time.
