One thing I appreciate about working out is that it's never as bad as I imagine it will be. While I'm working out I realize how much I underestimate my endurance, energy, and strength. The time moves by rather swiftly when I'm focused on the movement, too. I never regret following through with planned exercise. I'm glad and proud every time I push through until completion. The sense of personal achievement plus the wellness rewards from working out / exercising are so worth the imagined displeasure !
