What skills take less than 5 minutes to learn that everyone should know how to do? by Jake Croom
Answer by Jake Croom:
So I'm going to interpret the question as “5 minutes or less” with this ab exercise I do every day. Don't do it throughout the day, just once. It sucks at first- like your stomach is ripping apart- but after a while you will feel like a beast. This helped with confidence, as any workout plan would, and self esteem as I witness my abdominal muscles slowly form into what I've always wanted.
