You may find yourself thinking you need more mental strength so you can go to the gym. But what if the opposite were true? You need to go to the gym to build mental strength.
Most people focus on the physical muscle they build from exercise. But physical activity is also a great way to build mental muscle. 
Fortunately, you don’t necessarily need a gym membership to bolster your mental strength. There are plenty of physical activities you can do from home or outside to build mental strength.
You also don’t need to do torturous workouts that prove you can stand pain (a common myth about mental strength training). Sometimes, a few simple physical activities might be enough to help you feel better, think clearer, and gain motivation.
