Just because you don't have time to fit in a morning workout, doesn't mean you have to skip out entirely. Multitask while you're getting ready for work by fitting in lower body strengthening moves whenever you can. My favorite is doing sets of squats in the shower or while I'm brushing my teeth, blow-drying my hair, or waiting for my coffee to brew. Since squats are so effective at targeting your quads and glutes, it won't take many before you start to feel the burn. Do variations with your knees together, feet hip-distance apart, legs out wide, or heels lifted.
