Should you try trendy virtual classes? Yoga? Pilates? Do some dance moves? If you're looking to get lean and melt more fat, should you start training for a 10K or should you engage in high-octane bouts of high-intensity interval training? Even if you just want to walk your way to a healthier body, the options are surprisingly numerous: Should you stroll for longer distances, go fast, walk your nearest high-school football stadium steps, do Nordic walking, or perform interval workouts?
Well, if overall fitness is your goal, the leading fitness pros will tell you that they're all fantastic, and you should choose whatever workout you think you'll enjoy and stick to it.

It's Time to Pump Some Iron
Scientists have long known that building muscle mass via resistance training—or lifting weights—is crucial for transforming your body. Put succinctly, as Eren Legend, a celebrity trainer and accomplished bodybuilder, recently explained to GQ: "If you do cardio and you have a pear-shaped body, all that you can expect is to become a smaller pear. The only way to change your body composition, the shape and look of your body, is to perform a form of resistance-based training."

All-New Science Backs Him Up
Just last month, a new study published in the June issue of PLOS Medicine found that people who weight train several times per week were at "20-30 percent" less risk of becoming obese later on in life. The study notes that the link between weightlifting and obesity was "consistent among various subgroups," which include both genders and participants of all ages. Compared with no resistance training at all, those who lifted for 1 to 2 hours per week enjoyed the "lowest risk of developing obesity"—"suggesting that additional amounts of [weightlifting] might not be necessary to help prevent obesity."
But according to an eye-opening—and much-publicized—new study published in the Journal of the Federation of American for Experimental Biology, the reasons are becoming clearer. (Spoiler alert: It's not just because weight training simply builds bigger muscles.)
It's About Muscle Cells and Fat Cells
The scientists, led by a team from the University of Kentucky College of Medicine, discovered that weight training builds a relationship between your muscle cells and your fat cells that was hitherto unknown. The researchers knew that when you lift weights, your muscle cells release genetic material that scientists previously thought was simply waste, but in their experiment they discovered that your white fat cells actually pick up that released material, and, when it does, it triggers lipolysis, or the burning of fat.
"It suggested that you had muscle and fat communicating with each other via exosomes [or vesicles released from cells] and coordinating energy production," John McCarthy, Ph.D. a co-senior study author and associate Professor in the University of Kentucky College of Medicine's department of physiology, explained to the podcast Smart Talk. "[The study] contributes to an emerging appreciation for skeletal muscle. It's main function is to generate force and move your body, but maintaining muscle mass is important for overall metabolic health…. By building muscle mass, you're favorably impacting body composition." And if you really want a lean body? Make sure you Do This One Exercise Above All Others, Say Experts.
