I love to run—but I detest running uphill. When I hit an incline, my legs burn, I get acid reflux, and I often need to take a break to catch my breath. Jogging over hills is so terrible for me that I exclusively map out flat routes and sign up for races with minimal elevation, if any. As it turns out, there’s a legitimate reason people struggle with hills. Every single one of us has a unique running style, or running fingerprint, as John Mercer, a professor of Kinesiology and Nutrition Sciences at the University of Nevada, Las Vegas, calls it.

You don’t need to be deep in the fitness world to have run into the idea that cardio “kills” muscle gains—as if every cycling class and or 3-mile run sends a little army of molecules through your body to chomp away at hard-earned muscle tissue.

You might think electrolytes are some kind of lab-made superfuel for elite athletes and those who want to be like them. Electrolytes are indeed powerful, and in some circumstances, your body might benefit from a boost.

And like a movie franchise with one sequel too many, more is not always better.

Not all carbohydrates are created equal. While the complex carbohydrate is  an important part of a healthy, balanced diet—as they help us feel full and offer sustainable energy—refined or simple carbs typically increase blood sugar levels as high glyemic index (GI) foods and add very little nutritional value.

Baked potatoes have tons of benefits for your body. The potato skin, in particular, is the ticket.
