You always say you're going to do 200 crunches every time The Bachelorette comes on, but you barely make it through 20 before relaxing on the floor. These made-for-multitasking routines will keep you going until the credits roll.

1. The Routine That Makes You Appreciate Your Favorite Sitcom Even More

You can use a character's predictability to remind you to keep you moving -- sort of like a college drinking game, but with squats instead of shots. Love New Girl? Try this circuit workout from Mike Donavanik, a Los Angeles–based personal trainer and the creator of the Extreme Burn DVD series. Every time Schmidt says something offensively lame (which happens so frequently that his roommate have started a "douchebag jar"), use that as a cue to do one exercise for one minute. Donavanik recommends alternating upper and lower body moves: Start with push-ups, then squats, then tricep dips, then lunges. Finish with crunches. Keep cycling through these five exercises for the entire 30-minute show.

2. Strengthen Your Arms Without Ever Leaving The Couch

Tricep dips tone the muscles on the backside of your upper arms, Donavanik says, and the only piece of equipment you need is a sturdy piece of furniture. Position your hands on the couch on either side of your hips, and scoot your bottom off the edge of your seat. Your legs should be bent, with your feet placed hip-width apart on the floor. Slowly bend your elbows and lower your upper body until your arms are at a 90-degree angle (keep your back close to the couch). Straighten your arms and return to the starting position. Don't worry about counting; just do as many as you can, then rest. Repeat three to four times. While you should definitely feel the burn in this position, Donavanik says you can make this even more challenging by extending both legs straight in front of you or putting them up on a coffee table.

3. The Cardio Workout For When You Can't Be Bothered To Get Up

A portable pedal bike (which costs between $30 and $150) allows you to exercise in the comfort of your La-Z-Boy. These mini machines are much cheaper and take up less room than a stationary bike, treadmill or ski machine, but you have to be strategic to get your heart rate up. Skip steady-state cycling (which is easy to phone in) and do intervals instead. Start with a five-minute warm-up at easy resistance. Adjust the knob until turning the pedals takes moderate effort. Then do one minute of fast, intense pedaling, then one minute of easy -- and keep that up for the duration of the 30-minute program. (You can also take an "active recovery" during commercials by easing up on the resistance).

4. The Moves To Do When You Can't Take Your Eyes Off The Screen

Look away from Mad Men for one minute and you'll miss a symbolic detail or a key facial expression (or possibly a rare glimpse of Jon Hamm's bare torso). For these situations, Chicago-based personal trainer Traci D. Mitchell recommends wall squats, which she says strengthen the front and sides of the quads as well as the glutes. Keeping your upper back against a wall facing the television, take a big step forward. Sink down until you feel like you're sitting in a straight-back chair, with both thighs parallel to the ground. Mitchell likes to do pyramids: hold the squat for 10 seconds, then rest for a minute or so; hold for 20 seconds, then rest again. Keep lengthening the intervals until you get to 40 seconds, then take it back down (squat for 30 seconds, 20 seconds, 10 seconds). To work the shoulders at the same time, Mitchell says to extend your arms and lift them to shoulder height with each squat.

5. An Ab Workout You'll Actually Finish (And Feel)

The first rule, Mitchell says, is to stay off the floor -- that position makes it too tempting to grab a few cushions and stretch out. Instead of crunches, she recommends oblique twists that you can do while standing. Grab a heavy object, like a gallon of milk or water, and hold it with both hands. Plant your feet shoulder-width apart, tighten your core and extend your arms in front of you. While keeping your hips stable, rotate your torso and arms to the left, then back to center. Rotate to the right, and back to center. Do three sets of 20 reps.

  • Your Goal: Work Out At Least Four Times A Week

    You feel the most pumped to work out at night, but deadlines, family, friends and "Mad Men" have made it hard to stick to a schedule. Try picking an evening class (maybe even a pricey yoga or spin session) and treating it like a meeting or a social obligation. When you have a regular fitness appointment, you schedule the rest of your life around your workout instead of trying to fit your workout into your life, says Michelle Kennedy, MS, Best Life fitness expert. If that doesn't work, you may have to override your natural rhythms. The first week or two might be tough, but Kennedy swears a.m. workouts get easier over time. And she should know: because of her schedule and two young children, she needs to leave for the gym by 4:30 a.m. <b>Read more:</b> <a href="http://www.oprah.com/blogs/Ask-Bob-Greenes-Team-Whats-the-Best-Time-of-Day-to-Work-Out">The best time of day to work out</a>

  • Your Goal: Do Something About Your Tummy

    It's one of life's unfair truths: Your chances of washboard abs are mostly determined by your body type -- like how much extra weight you're carrying and where you're carrying it. But regardless of your abdominal DNA, you can build a stronger, more toned-looking core that can support your back, help you stand straighter (and therefore look slimmer) and lower your risk of injury. Skip sit-ups and crunches, and instead focus on planks: <a href="http://www.oprah.com/health/Essential-Exercises-Push-Ups-Downward-Dog-Squats-Planks/3">Here's how to do them correctly</a>.

  • Your Goal: Get Red-Carpet-Ready Thighs

    Squats are a big-name trainer's go-to move; you've seen them mentioned in articles about how this celebrity or that one got their pre-baby body back, or got fit for the beach scenes in their last movie, or prepared for that awards show. You know you can't easily spot-shrink the thighs nature (or your parents) gave you, but squats can help you reshape them. For those of us without trainers, doing squats right can be a little confusing. How low should you go? How should you hold the weights? Which way should you point your feet? <a href="http://www.oprah.com/health/How-to-Do-Squats-Exercise-Video">Bob Greene breaks it all down in this short video</a>. <b>Watch the video:</b> <a href="http://www.oprah.com/health/How-to-Do-Squats-Exercise-Video">How to do a squat</a>

  • Your Goal: Save Money On Gym (And Trainer) Fees
