Weights are king

Running is good. Biking is good. Swimming is good. Skiing is good. Walking is good. *Fill in your favorite mode of cardio—it’s good.* But no type of cardio will change and sculpt your body remotely close to that of strength training. If you want to change the way you look, lift the weights! (Oh. And weights do a lot more good than just make you look better, FYI.)
