To get the most out of outdoor sports such as hiking, rock climbing and mountain biking, you need to have a strong core. Rippling ab muscles not only look good but they also help get you over that one last ridge, up that last exhausting pitch, and through the end-of-the-run doubts that can plague the best of us.
The app provides illustrations of core-strengthening exercises plus a location finder to find a workout place, get a tan and do laundry. (GTL, Gym, Tanning, Laundry — it's a Jersey thing.) Suck it up and get ready to hurt, because you don't get as strong as The Situation without a little (abdominal) pain.
