No one likes going into the gym and doing the same thing over and over again. A great way to stay motivated is to do a variety of activities, instead of the same old boring one. This could mean you use a variety of gym equipment and machines, or it could just mean you work on different muscles on different days. Many people like to do a variety of real-life activities, such as golfing, hiking, and playing tennis or volleyball.
The activity doesn’t matter as much as the simple fact that you’re moving, and especially that you’re moving in a variety of different ways. Personal trainers and functional fitness gyms like CrossFit are good options if you don’t want to know how to create a variety of movements.
