Not sure how to jump start your path to fitness in the new year? As MNN’s series examining keys to health success in the new year continues, Steve Hintz, an exercise physiologist and founder of “Fitness First M-N” says if you want to boil it down to one area of focus, strength training can have a huge impact on overall fitness.

“We don’t’ have a problem in society with too much fat, we have a problem with too little muscle and all the adverse effects that happen as a result of the muscle decline.”

Hintz says it is the muscle that helps fuel constant metabolic activity throughout our daily routine.
