Hitting the open road has many benefits over running on a treadmill — fresh air and sunshine, gorgeous scenery to prevent boredom, and you can also run with your four-legged fitness buddy. You also have more freedom of movement to incorporate muscle-toning moves into your runs, and here's how.

- Run baby run: While running in general will tone your legs and booty, adding sprinting intervals is even more effective. Incorporate 30- to 60-second bursts throughout your workout and you're sure to feel your lower body working. Since you're outside, you can use landmarks to motivate you such as sprint to the stop sign or until you see five red cars, or if you're on a track, sprint the straights.
- Walk this way: Sprints aren't the only type of interval you can include. When you need to catch your breath after a sprint, throw in a few sets of walking lunges to target your glutes, quads, and hamstrings.
- Head for the hills: Find a steep hill in your neighborhood or in the woods and do hill repeats. Run up the hill then back down to target all the muscles in your lower body. If you need some motivation, try this hill repeat workout to build muscle and endurance.
