You can text.
You can work out.
You can’t do both. You have to decide. Try to do both and you’re just wasting time. Please get off the treadmill/elliptical/whatever machine and give it to someone who really wants to do something.
You’re driving everyone nuts. Please stop.
Hang up. Put the phone away. Get a real work out.
When you’re done, and only when you’re done, send me a text and tell me how well your workout went. Just don’t do them both at the same time, please.
