Every 20 minutes

Every 20 minutes, the timer goes off and I do 20 situps.
Sure, diet and walking can shed the pounds, but I carry my weight in my gut, so I needed to get better about targeting my trouble areas.
Situps are easy to do, and setting a kitchen timer to force myself to do reps over and over has been great about keeping the pace.
However, after a while, you can overdo it.
Hernias can be repaired, but lethal strokes can’t.
The timer goes off, and I feel a poke from the demon sitting on a stool.
“Do another twenty!”
