A new year, a new you. Getting in shape is one of the top goals set by people for the start of a new year. Many of us begin January with determination. We log hour upon hour in the gym, only to find our resolve weakening by the end of February or March. Where do all our good intentions go? The number-one reason that fitness goals fall by the wayside is time. It takes a decent chunk out of the day to get to the gym, get your workout in, and then shower and go along your way. Enter the beauty of workouts you can do at home—no travel time, tailored high-intensity workouts that are shorter in duration, no excuses. Check out our top five picks for fitness DVDs for workouts at home that will give you the results you want.

Jillian Michaels: Banish Fat, Boost Metabolism. Pop in this DVD by television’s top trainer. Fire up your metabolism and lose big with her fierce formula that adds strength and abdominal moves to dynamic cardio for increased fat loss. This workout consists of seven 6-minute circuits and doesn’t use any weights or equipment. All you need is a small space and a yoga mat (optional). It blasts your heart rate with challenging intervals to turn up the burn and peel off the pounds. It is perfect for any level, whether you are just starting a workout program or are a seasoned vet looking to shake things up. This workout provides full body engagement, plyometrics, and some serious core work for a combination that fires up your metabolism and banishes fat.

10 Minute Solution: Quick Sculpt Pilates. No time? Here’s the solution. Find 10 minutes in your day and commit that time to getting the long, lean body you want with Pilates. Again, all you need is a little bit of floor space and a yoga mat (this DVD comes with a toning ball to use if you want as well). Instructor Andrea Leigh Rogers guides you through five challenging routines to help tone your body and strengthen your core. If you have more than 10 minutes, mix and match workouts for quicker results. Choose from the Total Body Toner, Buns & Thigh Sculptor, Strength & Flexibility Training, Core Conditioning, and Standing Pilates Sculpt, and work your way toward your fitness goals no matter how pressed for time you are! Don’t forget to combine this with some cardio a couple of times a week to get the best results.

Jari Love's Get Extremely Ripped! 1000. The DVD has two high-intensity, body-sculpting 30-minute workouts, plus an ab routine that will help you work up a sweat. The title of the DVD alone tells you this is a serious workout. From beginner to advanced, modifications are provided for all skill levels. These workouts use interval training—a proven way to burn fat and calories and build muscle. They consist of 3-minute cardio circuits followed by a minute of strength training (so for this one you’ll need to pick up some dumbbells). Do each workout separately, or combine all three for an intense 75-minute session. This workout was designed in conjunction with medical professionals to provide optimal safety no matter what your fitness level.

Insanity Fast & Furious: Insanity is a well-known and reputable workout routine that will burn fat and sculpt your body in 60 days. The only downfall is that it requires you to dedicate 45 minutes a day to the workouts, and as mentioned above, time is often a limiting factor in our decision whether to work out in a given day. Enter Insanity Fast & Furious, the same heart-pounding, fat-burning moves condensed into a super intense 20-minute workout you can do when you’re pressed for time. Jumping, running, core work, ab work—all in one fast and furious routine! You could even use this workout to work up to doing the full 60-day Insanity routine, if you’re willing to commit to it.

TurboFire Greatest HIITs: Chalene Johnson leads you through 20-minute, high-intensity interval training (HIIT) workouts that will jumpstart your metabolism and push you to your max. With one-minute bursts of intense work followed by a short rest period, these drills will have you sweating and transforming your body in no time. This one includes demo videos to watch prior to starting the routines; these teach you how to do each move correctly—important because bad form leads to injuries, and injuries lead to ditching your workout. Again, this is an abbreviated version of a larger workout program (just search for TurboFire in your search engine) and can be used to ramp up to the full program. This DVD also includes a stretching routine that you can perform before and/or after the workouts to stretch out your muscles and reduce the possibility of injury.

Be smart—before starting a workout routine, always consult your physician to make sure your body is ready to handle the intensity of the program you want to use.
