Waiting for your tea to steep? Sneak in three sets of 25 countertop push ups. (My personal favorite.) I’ve done as many as 100. The next day sore, but oh so worth it. Another challenge I like to do is push-off the countertop edge as I come up (push-off mid to end of the rep). Careful not to miss the counter as you come back down! Give it try, and then reward yourself with a nice cup of tea!
