Learning Material: Feedback Loops Shape Your Fitness

Most people think transformation comes from big, dramatic changes, new workouts, restrictive diets, and intense challenges. But the human body is far more influenced by small, repeated signals than by sudden heroic efforts. This is the essence of a feedback loop:
tiny input → biological response → behavior adjustment → long-term outcome.

Key Insight

Why Feedback Loops Matter in Training

1. The body responds to patterns, not isolated events.

Muscles grow because the body repeatedly receives a message:
“Hey, these fibers are being challenged. Strengthen them.”
Missing one workout won’t erase progress, but consistent patterns, good or bad, shape the long-term trajectory.

This is why repeating a movement, even imperfectly, teaches your nervous system:

  • What “effort” feels like
  • How to recruit muscle
  • How to stabilize joints
    Your body is always learning from the signals you send.

2. Feedback loops can help or hinder you.

Positive loop:

  • eat enough protein → better recovery → more energy → stronger workouts → more muscle → higher metabolism

Negative loop:

  • poor sleep → higher cortisol → worse recovery → lower performance → frustration → inconsistent habits

Your job isn’t to be perfect, but it’s to nudge the loop in your favor a little each day.

3. Small habits compound like interest.

James Clear said it best: “Habits are the compound interest of self-improvement.”
Physiology agrees.

Examples of high-leverage micro-habits:

  • Drinking a protein shake during your “danger window” of the day
  • Going to bed 20 minutes earlier
  • Adding 2 slow breaths between sets
  • Practicing good posture while reading or typing

None of these feels dramatic. But repeat them 100 times, and they completely change your outcomes.

A Real-World Example

Think of your body as a garden.
Watering a plant with one big bucket once a week won’t keep it alive, but giving it a small amount of water daily promotes steady growth. Muscles behave the same way:

  • A single perfect workout won’t change much.
  • Consistent, modest signals, paired with recovery and nutrition, create the forest.

Your 100-day challenge itself is a feedback loop:
Train → reflect → adjust → grow.
You’re literally living the model.

Biometric data

Change in Weight from Day 1: -6.2 lb.
Skeletal Muscle: 39.8%
Muscle Mass: 93.4 lb.

My Reflection

Since I started working out, I’ve been paying close attention to the full system behind muscle development: protein intake, hydration, and sleep. I’ve learned the hard way that if even one piece is missing, the whole process becomes unstable and my progress slows.

In the past, I cared mostly about my body weight and appearance. That led me toward quick diets rather than sustainable habits. But when you eat too little, your metabolism struggles. I was exercising regularly, yet losing muscle because I wasn’t giving my body the protein it needed to rebuild. Looking back, I wish I had learned the basics of physiology earlier. I didn’t understand that without enough protein, training simply breaks down muscle faster.

The one thing I did right, even back then, was never quitting. Even when my weight fluctuated or my muscle mass declined, I kept moving, kept exercising, and kept trying.

Now I’m training much smarter. I understand how nutrition, recovery, and exercise work together, and I’m no longer chasing quick fixes. I’ll reach my goal weight eventually, but what matters most is continuing the process with patience and consistency.

Adjustment Ideas (Strategic)

  1. Identify one micro-habit that reliably improves your next-day metrics (sleep, soreness, mood, muscle mass). Make it non-negotiable for the coming week.
  2. Create a simple “feedback snapshot.” Each night, rate these from 1–5:
    • Protein intake
    • Sleep quality
    • Stress level
    • Workout quality
      This helps reveal patterns you can’t see day-to-day.

Introduce a tiny automation: pre-make your protein shake, lay out your workout clothes, or schedule 10 minutes for breathing. The easier the cue, the stronger the loop.

How I Beat the Humidity Boss and Logged My Second Fastest 10K

Written June 7, 2025

Hello Dear Readers,

This morning, I woke up feeling like a well-charged phone—ready to take on my first 10K of June. That enthusiasm lasted about thirty seconds… until my wife, aka the Morning Oracle, gave me a weather update: “It’s humid. Very humid.”

She’s always up at 5 a.m., doing her workout before the Nashville air turns into soup. I try to follow her lead, minus the pre-dawn drama—I have a bit more wiggle room in my schedule. (Perks of being flexible. Or at least pretending to be.)

But wow. Stepping outside felt like walking straight into a sauna hosted by the sun and a wet sponge. My wife, who once lived in Canada, still can’t get over Tennessee summers. She expected dry, crisp warmth—not a full-on oven door to the face every morning. Yet oddly enough, she loves living in Nashville. Go figure. Apparently, greenery and ultra-friendly neighbors make up for atmospheric soup.

And she’s not wrong. The people here are wonderfully nice. We’ve met most of them while running. Seriously—if you jog in our neighborhood, you’re basically signing up for a rotating social club on sneakers. Everyone’s out walking, running, or flexing their lawn-care game. It’s a charming vibe.

Despite the swampy conditions, I hit the pavement anyway. I’ve learned not to negotiate with my feelings in the morning. Motivation is a fair-weather friend—I prefer routines that don’t ask for permission. My wife says the same: “If I waited to feel like it, I’d never get anything done.” High-five to the discipline duo.

By the halfway point, I was just a second behind my target pace. But by the end? I actually clocked in two seconds faster. Take that, humidity boss! This run earned me my second fastest 10K ever, which, considering the weather, feels like unlocking a hidden achievement in a fitness video game.

The week overall? Not too shabby. I’ve been consistent with my workouts, though my upper body still feels the aftershocks of pushups and bicep curls. Sure, I’ll never win a protein shake endorsement deal (thank you, kidney-friendly diet), but I’m definitely stronger and happier than I was a few months ago.

So yes, today’s run may have felt like wading through a damp sponge, but victory tastes pretty sweet—even when it’s served with a side of sweat.

From Running to Strength: How I Built an Effective Upper Body Routine

Hello again, dear readers,

After running 1000 miles last year, I decided my legs were in the best condition they’d ever been, even before my stroke. Encouraged by my previous success, I expanded my exercises to include my upper body. I decided on pull-ups, pullovers, pushups, tricep pushups, and planks. These were all exercises I was previously familiar with and knew how to do, and they should help balance the fitness of my body a bit more. 

Next, I had to find a time/trigger for my exercises and determine how many to do. Since I’d been so good at keeping my running schedule, I used getting ready for my run as my trigger. So, every running day, before I head outside, I do some number of pull-ups, pullovers, pushups, triceps pushups, and planking. At the start of this routine, I only did one pull-up, one pullover, 21 pushups, one triceps pushup, and 1 minute, 21 seconds of planking. I found it easier to keep track of the goal numbers if they were aligned. 

I also decided that if I could achieve the target number 10 times, I would increase the number by 1. Eventually, I found that I could do two sets of exercises and did my first before I ate breakfast and my second before my run. In the beginning, when I was doing relatively small numbers of each activity, I tried to do four sets spread throughout the day. Still, I didn’t have appropriate triggers for 2 of them or 3 of them on non-running days, so I periodically forgot to do them all. Still, my before-breakfast set was reasonably easy to remember. I kept up with this set and have done it daily for over 200 days, gradually increasing my counts to 10 pull-ups, 10 pullovers, 20 pushups, 10 triceps pushups, and 1 minute 50 seconds of planking. There have been non-running days that I’ve missed the second set, but those have been rare enough that I haven’t worried too much about it.

So, after you’ve built and established a habit, consider using it as an anchor for expanding it into an entire routine. In making this routine, I prioritized rooting the practice over starting with higher/more challenging numbers. In the beginning, doing a single pull-up felt underwhelming, but I built the habit of slowly increasing the repetitions in my mind. I’m pretty confident that 10 successful sets aren’t optimal, but it’s easy to keep track of, and it’s working for me now. 

If it stops working, I must find a way to fix it. However, what matters most is that I am progressing and getting stronger.
