Can Electrical Stimulation Build Muscle and Speed Recovery? (Garrett Salpeter) | Ep 433
30/1/2026 | 1h
Get Fitness Lab (20% off for listeners), the #1 coaching app that adapts to YOUR recovery, YOUR schedule, and YOUR body. Build muscle, lose fat, and get stronger with daily personalized guidance.
—

If you train hard, want to build muscle, and still lose fat, how do you actually recover faster without breaking yourself down? Can electrical stimulation really support body recomp and strength training, or is it just another shiny gadget?
Garrett Salpeter joined me to connect the dots between neuroscience, rehab, and performance. We break down how early strength gains are driven by neural adaptation, why pain and restricted movement are often software problems not hardware ones, and where most recovery tools fall short.
You’ll learn why traditional TENS units underdeliver, how direct current stimulation works differently, and what the research shows for muscle building and rehab without excessive joint stress.

If you care about evidence-based fitness, smarter recovery, and training hard without burning out as you get older, this conversation will challenge how you think about recovery. Tune in to learn more.
Today, you’ll learn all about:
0:00 – Electrical stimulation myths
3:49 – Nervous system and strength
7:10 – Pain, protection, adaptation
15:08 – Fatigue and central governor
20:19 – Direct vs alternating current
31:40 – Muscle growth without load
35:45 – Real-world bodybuilding results
40:12 – Clinically designed recovery tools
50:40 – Regulation and real-world use

If you're over 40, cutting calories to lose fat can backfire.
Why? Because if your approach is too aggressive or your stress is too high, your hunger spikes, training suffers, and you often regain everything you lost when you increase calories again.
Body recomposition (losing fat while building or preserving muscle simultaneously) can avoid this. It's not just a physique strategy but also an appetite strategy.
In this finale of our 8-part appetite series, you'll learn why body recomp avoids the hunger cascade that derails most fat loss attempts.
Discover my Recomp Ladder framework that prioritizes your levers in the right order.
Get 3 ready-to-use body recomp plans: aggressive maintenance for efficiency-focused recomp, small deficit recomp for faster results without hunger, and the build-then-mini-cut approach for breaking plateaus.
You'll also learn who recomp works best for (hint: if you're over 40 with an inconsistent lifting history, you're in the sweet spot), the 5 most common recomp pitfalls, and a simple 2-metric check to know if your recomp is actually working (no scale weight required).
Timestamps:
0:00 - Do you actually need a deficit to lose fat?
3:20 - What body recomp really means (and what it's not)
5:22 - Recomp as an appetite management strategy
7:10 - 3 reasons recomp works better after 40
11:32 - Who body recomp works best for
14:43 - When recomp gets harder (and what to do instead)
15:53 - Appetite support during recomp
18:05 - The Recomp Ladder (5 levels)
21:42 - 3 specific plans for body recomp
25:04 - 5 common recomp mistakes and how to fix them
30:35 - Bonus: Quick 2-metric body recomp check (hint: NOT the scale)

Hungry after every workout and stuck in an endless “eat less, move more” loop?
Strength training is actually one of the most powerful appetite control tools you have, but most people only think of it as a muscle-building tool.
Learn the science behind why lifting suppresses hunger hormones like ghrelin while boosting satiety signals like GLP-1 and PYY. We cover why cardio often backfires through energy compensation, leaving you hungrier and more fatigued without the fat loss results. And discover the behavioral shifts that make strength training superior for long-term body recomposition.
Plus, get a template for building an appetite-friendly training week, cardio structured to avoid spiking your hunger, and a specific post-workout timing strategy to eliminate overeating at your hardest meal of the day.

What does it mean to "personlize" your fitness really?
In this episode, you'll learn about my ADAPT framework for personalizing fitness:
Assess your starting point
Do the thing (take action)
Analyze your data
Pivot based on what you learn
Test your changes
Learn why generic templates and YouTube workouts often fail, how to actually track progress beyond the scale, and the power of measuring energy and performance instead of just weight.
We also cover walking and NEAT (non-exercise activity thermogenesis), how to train around injuries without making them worse, building an effective home gym on a budget, and why patience and consistent data collection beat program-hopping every time.
This is from my conversation with Jenn Trepeck on her podcast Salad with a Side of Fries. Jenn is a health coach with an evidence-based approach to nutrition and weight loss who you may have caught on Wits & Weights last week discussing why your metabolism is stuck.
