Exercise at Home

My friend told me that she will stop her yoga class. She started three months ago and now she intended to do all what she learned before at home. She said practice at home can save the yoga course fees. Some more she claimed that she can practice whenever she likes. No need to chase for the class schedules.

I disagree with her decision. I still remember the last time she and me jogged at her home's treadmills. After one round she already failed up and asked for rest. Will she keep on exercise continuously at home? I don't think so. :P
