What makes your workout effective? Is it how hard you work? The science behind your routine? Maybe it’s how you feel afterward?
All of those things are certainly important, but those things can also be very misleading and fool you into believing your workout is more effective than it really is.
The real key to an effective workout is understanding just what objective you want to accomplish from your training. What do you want to teach your body to do? That’s the key to more efficient and more effective workouts.
