1. Bicycling
   Preacher curls
2. Pilates
   Yoga

Cycling is a fantastic cardiovascular exercise, and it will build muscle in your legs. However, you'll need to put in some time in the weight room to keep your upper body in shape, and to counteract those characteristic slope shoulders of someone who spends a lot of time hunched over the handlebars.

1. A Bosu ball
   Hand weights
2. Weight machines
   Resistance bands

A Bosu ball looks like a Swiss ball cut in half and put on a flat base. It's most often used for balance exercises, as part of a stretching routine. However, you could probably adapt a strength-training exercise to be done on a Bosu ball.

1. True!
   Not so!
2. Ehhh ....

Some people have marvelous success with high-fat diets. But the key is, you still have to run a calorie deficit. If you're eating 2,400 calories a day and burning only 1,800, your body will turn the rest into fat -- no matter what. Fat calories do not have any kind of magic pass to get through your system without adding to your body's fat stores.

1. It doesn't take calorie-counting into account, and fat has twice as many calories per gram as carbs or protein.
   Fat takes longer to make you feel full, allowing overeating in the short term.
2. It doesn't take heart health into account.
   All of these

The research on "keto diets" is ongoing, and remains complex. However, there are some red flags, like the specter of heart attack and stroke risk if dieters don't choose healthy fats. And with lipids having 9 calories per gram compared to 4 for protein or carbs, there's also a potential for overeating, especially during the period before slow-burning fats raise your blood sugar and signal satiety to your brain.

1. Aerobic dance
   Triathlon
2. PX90
   Yoga

Yoga comes from India, and much of its vocabulary is from the Hindi language. So while you'll often hear people refer to "poses" in yoga, the traditional term is "asana." (Don't confuse it with sweating out toxins in a small, pine-paneled room.)

1. Bridge
   Core
2. Solar plexus
   Stem

Core is a gym term so, you don't really hear the word in a doctor's office. That doesn't mean it's not valid, though. Core exercises are very important for balance and stability, and increasingly needed as you age.

1. Cross-fit
   Quad training
2. PX90
   Spinning

The name "spinning" was coined by Johnny Goldberg, a South African competitive cyclist who elevated the use of indoor stationary bikes to a new level, using equipment that resembled a racing bicycle and creating classes with music. Though used interchangeably with "indoor cycling," "spinning" is actually a trademarked term.

1. True
2. False

Cross-training keeps your body "on its toes," so to speak; the challenge is good for you. Sticking to one exercise regimen for too long, on the other hand, can lead to diminishing returns as your body gets used to it and isn't challenged.

1. Aerobic
   Anaerobic
2. It's usually aerobic, but bursts of anaerobic exercise are possible.
   These terms do not apply.

People think of running as good aerobic exercise, and they're right. However, sprinting is anaerobic, putting a great demand on muscles and producing lactic acid. That's why, like other forms of anaerobic exercise, it can't be sustained for a long time.

1. They spread germs more readily.
   They don't build muscle as easily.
2. Jocks cluster around the free weight rack.
   You can hurt yourself more easily.

Weight machines have a limited range of motion; the correct exercise is sort of "programmed in" to how the machine is built. With free weights, there are no such limitations, allowing the user to extend past a healthy range of motion and injure himself or herself.

1. Your muscles need rest between training days.
   It's OK to do a full-body workout all in one day.
2. It's always good to ask fellow lifters for advice on form.
   It's important to train all major muscle groups.

A better way to say this is probably, "Be careful when asking for advice." Some lifters know what they're doing, but others learned the wrong way from someone else who learned the wrong way, and ... well, you see the problem. If necesssary, book a session with a personal trainer.

1. Before going to the gym
   At the gym, before your workout
2. At the gym, after your workout
   The next morning

Some of you might be surprised that "stretch before your workout" is no longer the reigning advice. That's because your muscles are too "cold" to stretch effectively then, and pushing too far into a stretch at that point can lead to discomfort or injury. It's important to warm up or start exercising slowly. But don't stretch until after the workout's done.

1. The body's use of oxygen
   The body's creation of oxygen
2. The air visible between one's shoe and the ground during exercise
   The potential for muscle growth

In aerobic exercise, the body works at a more-or-less steady state and requires a steady supply of oxygen at higher levels than it does at rest. It's a term closely related to "cardio." Anaerobic exercise is one with an intense, short burst of power -- weightlifting is a good example -- that doesn't require as much oxygen.

1. Eight
   10
2. 12
   There is no fixed number.

In lifting, a set is however many reps adequately challenge you. For some reason, many weightlifters favor sets of even numbers: 10, 12, 18. Pro tip: To be left alone at the gym, tell people you always do sets of eleven, then defend it with a complicated numerological theory about prime numbers being best for gains. People will thereafter let you work out in peace.

1. The point of muscle failure
   You lose count
2. You get bored
   The gym closes

"Muscle failure" means that the body part being exercised feels a little wobbly, and you can't keep good form. It *doesn't* mean to keep going until you let the weight crash to the ground (or back down onto the other weight on the rack, in the case of a weight machine). Despite the drastic name, muscle failure is a good thing for gains.

1. Before lifting
   After lifting
2. At the midpoint
   It doesn't really matter

Some fitness buffs have theories about this, and they'll staunchly defend their decision to do cardio before or after weights. But there's no good evidence that one is a better choice than the other.

1. CrossFit
   Fencing
2. Running
   Swimming

Swimming, in which the body is supported by water and motions are fluid, is a good form of exercise for people with joint pain. The other three are weight-bearing exercises, some with sudden movements, that wouldn't be appropriate. Of course, this is assuming the person in question has mild joint issues. For more severe forms like rheumatoid arthritis, a doctor's advice is needed before starting any exercise program.

1. 30 minutes
   45 minutes
2. Two hours
   It doesn't seem to matter

Beware the Cult of Supplementation! Its followers are everywhere, their blenders constantly awhirr with the makings of protein shakes, stopwatches at the ready to tell you that you've missed the "anabolic window." Don't believe it: Getting a good mix of protein, carbs and fat at regular intervals throughout the day will serve you just as well.

1. Gluteals
   Latissimus dorsi
2. Quadriceps
   Both "glutes" and "quads"

Squats are a leg exercise. The main muscle groups they work are the quadriceps (in the upper leg) and the gluteals (your rear end). How you perform a squat will affect where most of the effort takes place, so practice your form carefully for best results.

1. An elliptical machine
   A stairclimber
2. An upright bike
   A rowing machine

Many pieces of stationary cardio equipment focus on the lower body: The classic stationary bike, the treadmill, the elliptical (despite the moving hand-grips). But a rowing machine works your chest muscles, while getting your heart rate up, too.

1. Bench/scale
   Chest/booty
2. Weight rack/spinning studio
   Gym/table

"Muscle is gained at the gym; weight is lost at the table." Keep this phrase in the forefront of your mind, and you'll never go wrong. What it means, essentially, is that only by controlling eating do you control weight. We might add, to the first half, that "cardiovascular fitness" is also gained at the gym, not just muscle.

1. In your upper arm
   In your lower arm
2. In your back
   Near your abs

The trapezius muscle runs from the back of the neck through the upper back. Exercises that give it a workout include deadlifts, dead rows, and "lat pulldowns," though the last primarily focuses on the latissimus dorsi, as the name implies.

1. Triceps
   Soleus
2. Pectorals
   Rhomboids

This name might remind you of geometry class, and there's a reason. The rhomboid muscles have a roughly parallelogram-like shape, like the rhombus. The rhomboid muscles benefit from all the back exercises: deadlifts, clean-and-press, etc.

1. Kundalini
   Iyengar
   Ashtanga
2. Vinyasa
   Both Ashtanga and Vinyasa
   Both Kundalini and Iyengar

Ashtanga yoga is physically challenging, and deserving of the Westernized term, "power yoga." Vinyasa is an outgrowth of Ashtanga, but focuses more on a flow of one pose to another, creating a type of aerobic exercise.

1. Abdominals
   Biceps
2. Triceps
   Shoulders

Exercises like the "clean and press" can develop your shoulder muscles. Then, once it's nice and round and defined, go out and get a gorgeous sunflower tattoo to show it off! (At least, that's what we'd do, if we had great delts).

1. Gymnastics
   Interval training
2. Powerlifting
   Powerwalking

A CrossFitter wouldn't be caught dead just walking, no matter how speedily! CrossFit (another trademarked name that is quickly becoming generic) is a mix of high-intensity floor exercises, heavy weightlifting, calisthenics and more. It has been criticized for its high rate of injury.

1. Growth
   Little mouse
2. Little lion
   Strength

What?! Yes, it's true! "Musculus" means "little mouse" in Latin. It's not clear how the word came to be applied to muscles -- it's possibly due to how the muscles look moving under the skin. However, it certainly isn't very inspiring when you're getting ready to lift!

1. The bicep
   The masseter, or jaw
2. The quadricep
   The trapezius

Isn't this "news you can't use" when it comes to fitness? No one goes to the gym to work out their jaw! But it's a fascinating piece of trivia nonetheless, and one that might have its roots in evolution. Maybe our survival depended less on raw strength and more on our ability to chew up tough, seemingly inedible things!

1. Ashtanga
   Kundalini
2. Manipura
   Vinyasa

This one was probably tricky, we know, because all the words above are from Hindi, the language associated with yoga, which is itself East Indian in origin. But "manipura" is the name of one of the chakras, the third chakra near the solar plexus.

1. Hot yoga
   Power yoga
2. Restorative yoga
   Pilates

In Bikram yoga, you'll practice in a studio that has been heated to about 105 degrees Fahrenheit. There's often a humidifier at work. This is to help you break a sweat. Or you could just move to Georgia and do your yoga outside.

1. Take a few days off
   See a doctor
2. Start taking an iron supplement
   Show off your gains!

"Hypertrophy" sounds scary, but don't worry -- it just means growth! Weightlifters call this "gains," or, for maximum effect, "sick gains!" How much hypertrophy you can experience will depend on factors like your age and sex, as well as your diet.

1. Calisthenics
   Jazzercise
2. Pilates
   Plyometrics

Yoga and Pilates are often mentioned in the same breath. If you think of Pilates as "yoga without the philosophical element," that's not entirely true. Joseph Pilates, who created it, considered Pilates to be a mental-health exercise, with focus on the breath and finding the body's "center."

1. Extreme stretching
   Jumping
2. A pool
   Resistance bands

Plyometrics uses repeated jumping (often onto a box or platform), to increase an athlete's explosive power. It was pioneered by Russian trainers, but the name was coined by an American Olympic athlete who observed Russian athletes doing plyometrics in their warm-ups.

1. Fun
   Fundamental
2. Medicine
   Vital

The "Exercise is Medicine" initiative calls for doctors, physicians' assistants and other healthcare providers to ask every patient about their activity levels. It also recommends writing an "exercise prescription" when appropriate. Hey, we're on board!

1. Cardio
   Sudoku
2. Stretching
   Strength training

Sudoku is great exercise -- for your brain! We certainly don't want to tell you *not* to do these Japanese puzzles. But a good gym regimen is a "tripod," with cardio, strength training and stretching.
