Pilates is a form of resistance training that focuses on strengthening your core as well as maintaining and improving flexibility. Although Pilates is for overall strength, the focus is different than traditional strength training. Proper technique, alignment, and breathing are emphasized along with focus. Resistance training that is not Pilates-oriented typically places a heavier load on muscles. Although your core is working in most exercises in order to stabilize the spine, the goal is more geared toward strengthening muscle groups that are moving the resistance. The goal is often geared more toward changing body composition in order to build lean muscle and decrease fat stores which in turn increases resting metabolic rate.
