I use the Spawn Super Exercise Program. If you think about doing exercise, its just as good as actually doing it.
Spawn, that's better than nothing.

Yue and his colleagues have already found that mentally visualising exercise was enough to increase strength in a muscle in the little finger, which it uses to move sideways. Now his team has turned its attention to a larger, more frequently used muscle, the bicep.

Thought experiment


They asked 10 volunteers aged 20 to 35 to imagine flexing one of their biceps as hard as possible in training sessions five times a week. The researchers recorded the electrical brain activity during the sessions. To ensure the volunteers were not unintentionally tensing, they also monitored electrical impulses at the motor neurons of their arm muscles.

Every two weeks, they measured the strength of the volunteers' muscles. The volunteers who thought about exercise showed a 13.5 per cent increase in strength after a few weeks, and maintained that gain for three months after the training stopped. Controls who missed out on the mental workout showed no improvement in strength.
 
What, in this heat, it must have near killed you.

Hope that you had a sixpack of malt beverage to help replace all of the electrolytes that you were imaginarily losing.
