You're not alone if you're having trouble starting or following through on a fitness plan. Even I—and other fitness pros—can face this challenge in our lives. Seriously!

An all-or-nothing attitude may get in your way. Research shows that a little exercise is better than none. It’s not necessary to spend hours in the gym or do endless monotonous routines.

Don’t beat yourself up because you think you lack willpower. Negative self-talk only demotivates you.

This is what you should do instead.
