No you don’t understand its a new thing now the chair exercise for people over 50’s men and women. Even now the younger people are now doing it. Actually everyone is now doing it. I think it started from America or China I’m not too sure. Its to remove tummy fat, farm leg Muscles, Firm inter thighs muscles, back muscles belly muscles and so on. No I Certainly do not sit around all day. I do the chair exercise first thing in the morning on a empty stomach, and last thing at night before bed. You should try it only 10 or 15 minutes per day. You feel much better in days!! Anyway it’s keep me looking younger..lol.hehe
