The LO Maglev are The fastest trains in the world at 375 miles per hour. They utilize Magnetic Levitation to ride, without friction, scant inches above the track. That small adjustment of a, all few inches makes the LO Maglev faster and more efficient than conventional trains. Comparatively Small adjustments (inches) can create giant breakthroughs in the gym.
For instance, small tweaks to your diet can create huge breakthroughs. A weekly caloric deficit of 350 calories leads to a 5 lb weight reduction over a year. That’s 50 calories a day; basically 2 bites of chocolate cake.
Small adjustments
In similar fashion small gym adjustments to your workouts may be all you need to make similar breakthroughs.
The most compelling evidence: your hamstrings.
Everyone has tight hamstrings; Moreover, EVERYONE stretches them wrong.
Let me illustrate. Touch your toes.

Feel that hamstring stretch directly behind your knees? These are not your hamstrings. What you’re feeling are ligaments. They do not stretch: They tear. That explicitly defeats the purpose of touching your toes, huh?

Now stretch with a bent knee, just an inch. Feel that? That’s your hamstring; somewhere midway up the back of your thigh. Evidently a small adjustment created a measurable result (see below).

Getting fit isn’t as hard as most people think. Just 11 minutes of exercise a day has a profound effect on your health and longevity. You may think you need to do something drastic like run a marathon, or go vegan to get fit; but small adjustments of just a few calories or adjusting by an inch can make big difference.
Knowing which micro adjustments to make… That’s the hard part. Sometimes that necessitates a Coach.
A Trainer.
