Switch Up Your Cardio: 30-Minutes of Intervals on the Bike
While it's often overlooked at the gym, the exercise bike can help you burn tons of calories and tone your legs. When working out on a stationary bike, the trick is to make sure you have the machine set with enough resistance. This way, you won't pedal yourself off the bike, but you'll also be able to sprint when necessary, which can make for a great interval workout.

Mixing up the pace challenges the heart and lungs, but interval bike workouts also prevent boredom while pedaling on a road to nowhere. Keep reading to check out this interval workout.
Box Jumps: The Possibilities Are Endless
The next time you're at the gym, elevate your workout with box jumps. A popular exercise among athletes and in CrossFit workouts, box jumps test speed and agility while also increasing your heart rate. To do this plyometric exercise, all you need is a box (solid or padded) or an elevated platform. Depending on your fitness level and goals, use a single box to improve your agility or stagger boxes for obstacle-testing efficiency. Before you get jumping, keep these tips in mind:

- Consider your box height: First things first, consider the height of the box. On average, most boxes are between 12 and 24 inches. If you're solely testing your vertical ability or doing a singular jump, a taller box is appropriate. But if you're testing speed or creating a course, consider smaller boxes or staggering those of different heights. Remember, you can also work your way up. Always start lower to prevent injury and get comfortable with the movement.
- Create a workout for your goals: Your goals should determine how and what type of box jumps you do. If you're starting out, you may only focus on the "jump," then step down. If you're looking for a cardio workout, do several jumps in a row. To improve your balance, try jumping with one leg.
- Use your entire body: Although jumps are primarily a lower body move, they do work your entire body. Use your starting position to set up the entire movement: engage your core, bend at the knees, and allow your arms to provide you with momentum. Relying on your entire body will affect your stance and help you stay light on your feet.
