12 Major Workout Mistakes To Avoid In 2018

Cardio is great for your heart health, but doing just cardio robs your body of the benefits of strength training. Lifting weights could change the shape of your body while keeping your bones and joints strong too. 

"Cardio isn't going to change the shape and the look of your body," she said. "Strength training is going to burn calories, change the shape and look of your body, and you're going to continue to burn calories post-workout because it requires energy to actually build muscle." 

To successfully implement both into your routine, Fried compared a workout to a dinner plate. "If you have a plate of food, strength training should be your meat and potatoes and cardio is your side dish," she said. "You want to eat the main portion first and get the strength training done, since that's your priority and the main part of your workout, and then cardio should really be looked at as something you sprinkle in as needed." Although a cardio-only routine could help you lose weight by burning calories, strength training takes the cake regarding a time-effective workout.
