If you want to hit the gym and work purely on developing showy muscle like your abs and biceps, then all power to you – we’re not going to rag on anyone who’s going to the gym. However, if you want to get better at the serious lifts and build an all-round stronger body, then you need to spend time on your core as well. Fortunately working the core is something you’re probably doing already, because so many exercises involve it. ~ Berceste
