Exercise: Couch Bike
Situation: Kicking back in the sofa
A good little Nano Workout you can do when kicking back in the sofa at home. You can also try to do it on a smaller chair e.g. at the office.
Lean back and rest on your elbows. Cycle with your legs for as long as you can. Take a rest and do another set..or two. Your abs will also get to work a bit in this exercise.
