If you're workout is stuck in a rut, it's time to shake things up for the next generation workout classes that combine disciplines. Such as, what do you get when you blend muscle-lengthening yoga moves with core-toning Pilates principles? A workout combo known as SLT, which sculpts your whole body. Practicing twice per week will yield impressive results (Chrissy Teigen is a regular—'nuff said), but it's no easy ride, even for seasoned gym-goers: Prepare to burn more than 500 calories while doing an intense mix of cardio and strength training. Since you'll be doing some serious sweating, look for moisture-wicking capris and sports bras. Trust us, you'll want to be plenty hydrated for this one.
