Being Too Focused on One Thing
It's important to find a workout you like so you keep doing it and stay committed to your fitness goals. However, it is possible to have too much of a good thing.
"I see a lot of woman who are just runners or who just lift or just Spin," Jim told POPSUGAR. "It is important to get a variety of exercise disciplines in to decrease boredom, work different muscles, improve flexibility, and engage the heart." So if Spinning is your workout of choice, try doing it a couple days a week interspersed with days of weight training instead of just going to Spin class five days a week.
