Maybe have a situp and pushup catchup instead? Worst case scenario they fall asleep on the ground!
Sounds like that would be the best case scenario.
It would be an excellent way to deter them.... mmmm. They already think I'm crazy so no harm done.
if they can't get off the ground they can roll to their vehicular transport.
ha ha! I think if a blood tests were done the % of caffeine would be huge. Much of their usual exercise is walking from carpark to coffee shop.... harsh but fair.
