Consistency is king.

If you’re considering a certain training methodology, or wondering about a specific diet, it’s helpful to ask yourself:

“Will this help me be consistent?”

If the answer is yes, that’s a good sign.

If the answer is no, it may be wise to reconsider.

The best approach isn’t always the one that’s “optimal.”

It’s the one that helps YOU stay consistent, week after week, month after month, and year after year.

And that often looks different from runner to runner.

This is a big part of what 1:1 coaching involves - collaboratively finding what works for you, within your schedule, your preferences, and your life, to finally create lasting change.

The running, the strength, the nutrition, the injury-prevention work…feels like a lot.

Ain’t nobody got time for all ‘at (as the kids say).

The BEST news is, though…

When running, strength, and nutrition are aligned to YOU, the system to losing weight, running pain-free, and feeling at your best is both simple AND time-friendly.

It doesn’t require hours at the gym, on the treadmill, or making meals.

It just requires the RIGHT habits - the ones that are actually worth doing for YOU, done mostly consistently.

So that your running is taking off, the scale is trending in the right direction, and injuries are all but a distant memory.

YOU can be an injury-free, lean, and healthy runner.

Running social media tends to make things more complicated in a world that, I believe, needs more simple.

You will go very far through mastering simple.

As a physical therapist and certified run and nutrition coach…

And as someone who experienced a myriad of running injuries, then ran pain-free…

And as someone who gained weight, then lost weight…

And as someone who helps others run pain-free and lose weight…

I can confidently tell you that it is only when training, nutrition, injury prevention, and lifestyle factors work TOGETHER that we feel and run at our best!

This doesn’t always mean more hours devoted to these things…

It simply means finding the right, worthwhile “inputs” and learning how to practically fit them into your unique life.

Runner-specific strength work, mostly whole foods, good sleep hygiene, sensible training progressions…

It all supports each other, directly or indirectly.

You feel better physically and mentally, the ball starts rolling, momentum builds, and you’ve finally found the practical routine that works in YOUR life to help you lose the weight, keep it off, run consistently, and stay injury-free.

THAT is when you get the lasting, enjoyable, and FUN results that you want!

This is a big component of what we do in 1:1 coaching - finding out exactly what levers to pull and systems to implement so you actually follow through and get results, for good.

All-or-nothing mindsets often hinder results.

As a coach, I preach “80% consistency” to my runners, as this is a much more realistic standard to shoot for than perfection.

This isn’t just for training, either. Same concept applies to nutrition. 80% consistency in the right nutrition habits will drive results for most.

There’s a tension between holding yourself accountable and allowing grace for missing a workout or nutrition habit.

And I believe 80% consistency is a great objective gold standard to hold yourself accountable to.

For many of my runners that struggle with an all-or-nothing mindset, this proves to be a game-changer in their running and health.

If you resonate with this and would like to lose 10-30+ pounds while becoming a pain-free runner, let’s talk!
