If you’re looking to earn the coveted “six-pack”, then swimming is an excellent means of burning fat while improving your core muscles. Core muscle development and growth is crucial to the shape and form of your abdominals, and once the fat has been dusted off … you’ll be strutting proudly in your swimsuit. Have you been watching the American Olympic swimming trials? If so, you’ve no-doubt been blown away by the abs of Michael Phelps, Ryan Lochte and a slew of other swimmers. Whatever your current work-out plan or fitness level, adding intense swimming sessions is a smart idea. Swimming vigorously ranks high in the “intense workout” category, so if you do it often and combine that with wise eating habits … you’ll be surprised by how quickly your hard work in the pool yields results.
