Increase resistance: If you enjoy walking, add some hand weights or ankle weights to your routine. If you're a fan of the elliptical machine, increase your resistance level so you can get that heart pumping again. And if you've settled for the treadmill or exercise bike, take things up a notch by completing a hill workout or interval training; the goal is to challenge yourself and push just a little harder so you're not doing the same old routine over and over again.

Head to fitness camp: Fitness camps are readily available at resorts and spas around the country -- it's a chance to try new workouts, meet other fitness enthusiasts and learn some new exercise routines. If you can't afford a complete vacation, consider joining a fitness club or group in your area so you can recommit to your fitness routine and work out with friends in the process.

Don't let boredom hold you back from reaching your fitness goals; jump into a fresh new routine or modify your existing one so you're challenging new muscle groups, revving up your metabolism and having fun in the process!
