It sounds too good to be true and for now, it is. But what if some of the benefits of exercise could be packed into a pill? Scientists are beginning to develop “exercise pills” that show some potential, according to two [new papers—a review](http://www.cell.com/trends/pharmacological-sciences/abstract/S0165-6147%2815%2900187-X "undefined") published in the journal _Trends in Pharmacological Sciences_ and another small study published in the journal [_Cell Metabolism_](http://www.cell.com/cell-metabolism/abstract/S1550-4131%2815%2900458-1 "undefined").
“Everyone’s looking for a pill to replace exercise, but we’re just not there yet,” says the first study’s co-author Ismail Laher, professor in the department of anesthesiology, pharmacology and therapeutics at the University of British Columbia in Canada. “It’s not going to make a couch potato into Arnold Schwarzenegger.”

So-called “exercise pills” are made from compounds that have been shown—mostly in studies done in animals—to mimic one or more of the effects of exercise, like developing new blood vessels, forming new mitochondria in cells or increasing the body’s capacity for exercise. “They’ll let you get muscles that are stronger and faster and reach your exercise goals much quicker,” Laher says.
But no single pill can reproduce every benefit exercise has on the body. Popping an exercise pill won’t flood you with endorphins, for instance, while also making your bones stronger. speeding up the blood flow through your arteries and making your heart beat faster, Laher says. “It’s a very small slice of the pie.”
What exercise pills _can_ do is largely localized to muscles, the new review finds. “You’re increasing efficiency of ATP, the currency by which every cell goes about its daily life,” Laher says.
### QUIZ: Should You Eat This or That?
Which is better for you: Half cup of ice cream or 3 scoops of sorbet? Getty Images (4)
Answer: A half cup of ice cream If you eat what you’re craving, you’re more likely to feel satisfied and eat less. And scoop for scoop sorbet contains twice the sugar with none of the filling dairy protein and fat. Getty Images (5); Gif by Mia Tramz for TIME
Which is better for you: Real butter or spray on fake butter? Getty Images; Tara Johnson for TIME
Answer: Butter Serving size for spray butters (even low-calorie ones) are around a 1/3 second spray. What on earth does that mean? You're better off using a small amount of real butter as opposed to guessing how much you're using of the mystery melange of up to 20 ingredients. Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: A turkey burger or a sirloin burger? Getty Images (2)
Answer: Sirloin burger Restaurant turkey burgers are often made with dark meat and the skin, so they’re not necessarily better for you (and for the record, they aren't low-fat). You can get a sirloin burger that’s 95% lean meat and gives you 20 g of protein. Just be careful with the toppings. Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: Almonds or pretzels? Getty Images (2)
Answer: Almonds Almonds are high in protein, fiber and fat and will keep you feeling fuller longer. Give high-sodium pretzels about an hour and you'll feel hungry again thanks to the high-carb no-fat or protein content. Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: Special K or eggs? AP; Getty Images
Answer: Eggs In the morning, you want a meal that will fill you up. Eggs offer protein and fat for satiety, but Special K cereal really only offers carbs and, well, air. If you want carbs to kick off the day, you're better off pairing eggs with a slice of 100% whole grain toast. Getty Images (1); Gif by Mia Tramz for TIME
Which is better for you: Fat free salad dressing or regular salad dressing? Tara Johnson for TIME
Answer: Regular salad dressingTo absorb fat soluble vitamins like Vitamins E and K in vegetables you need to consume them with a fat to aid nutrient absorption. Fat-free dressing, meanwhile, is low-calorie but gets its flavor from added sugar and salt. Tara Johnson for TIME (5); Gif by Mia Tramz for TIME
Which is better for you: A low fat cookie or dark chocolate? Getty Images (2)
Answer: Dark chocolate “People believe fat free is calorie free,” says Keri Gans, a registered dietitian in New York City. “Go for the real thing.” Fat free cookies tend to be high in carbs, sugar and fake sugar. Try a nice piece of antioxidant-rich dark chocolate instead. Getty Images (2); Gif by Mia Tramz for TIME
Which is better for you: Low fat Greek yogurt or 100 calorie Yoplait yogurt? Tara Johnson for TIME
Answer: 2% Greek YogurtA little fat is good in the morning to keep you full—plus it has upwards of 17g of protein per container. Fat-free "fruit" yogurt is high in sugar—7 to 10 g per serving—and lower in protein. Tara Johnson for TIME (2); Gif by Mia Tramz for TIME

In the second study, researchers biopsied the muscles of four healthy men after they exercised vigorously for 10 minutes. After analyzing the samples, the researchers discovered 1,004 molecular changes in the muscle—most of which scientists hadn’t before attributed to exercise. “While scientists have long suspected that exercise causes a complicated series of changes to human muscle, this is the first time we have been able to map exactly what happens,” said study co-author Dr. Nolan Hoffman, of the Charles Perkins Centre and Faculty of Science at the University of Sydney in Australia, in a statement. This new research, he said, would allow scientists to use this information to design a drug that mimics the positive changes from exercise.
The real promise of exercise pills is not to replace exercise, Laher says, but to help people who have reduced muscle ability due to paralysis, obesity, stroke or spinal cord injuries. For those who aren’t physically able to exercise, the hope is that they can recover more muscle control when they use pills alongside physical therapy.
The quest for the exercise pill has been ongoing since 2004, and the review looks at several compounds that can trigger at least one beneficial exercise effect. Before any single one is determined to be the silver bullet, much more research—in humans, especially—is needed. Scientists also have to figure out effective dosages in people and possible side effects.
Even with the promise of these compounds, sweating isn’t off your to-do list. “We’re in early days,” Laher says.
