Your Muscles Need a Vacation Too

Hey {{first name | reader}},

It’s Tuesday, which means your weekly fitness check-in. Welcome to Week #21.

I’m taking advantage of the long weekend to reset and evaluate my progress, conveniently while on vacation on the Big Island of Hawaii. Most days I like to push myself in the gym and increase the weight I’m lifting as quickly and aggressively as possible. The reality is that sometimes progress requires pulling back. Vacations help force this on me.

My hotel gym is split across two windowless basement rooms — one has the cardio equipment, one has the weights, and neither has windows. The Pacific Ocean is a seven-minute walk away. The decision about where to spend my mornings this week has not been difficult.

I’ve been doing shortened sessions, getting outside, and reminding myself that this counts as training too.

We underestimate the importance of recovery when we’re determined to build muscle and get stronger.

A friend recently asked me what would happen if she deadlifted every day.¹ The answer is not “faster progress.” The answer is that eventually she’d break down her muscles faster than she could repair them and likely get weaker over time.

When we lift weights, we create tension in the muscles and tiny tears in the muscle fibers. The repair process is what actually makes us stronger. Without recovery time, there’s no opportunity for adaptation — just repeated breakdown.

The general rule of thumb is about 48 hours before heavily training the same muscle group again.²

The other reality is that we can’t keep lifting the same weight forever and expect results. Eventually the body adapts. If the stimulus never changes, the muscle has no reason to grow.

People often ask how quickly they should increase weight. Unfortunately, this is more art than science. We all progress at different rates. Personally, I try to increase weight every one to two weeks. For upper body exercises, that usually means 2.5–5 pound jumps. Squats go up by 5 pounds. Deadlifts by 10.

I know it’s time to increase the weight when I can comfortably hit the top end of my rep range across all working sets without feeling like I’m fighting for my life.

I also deliberately back off after about eight weeks of steady progression. I’ll do an easier week with lighter weights and higher reps. Those weeks are less about ego and more about mechanics — cleaning up form, slowing things down, and fixing the little compensations that start sneaking in once the weights get heavy.

Then I go right back to loading the bar again.

I also rotate exercises every couple of months while still targeting the same movement patterns. If I’ve spent a training cycle focused on back squats, I may switch to front squats. If I’ve been hammering heavy RDLs, I may swap in good mornings.

Same muscles. Different emphasis. Slightly different ways to suffer.

The point of the rotation is the same as the point of this week — interrupt the pattern before the pattern stops working.

Question: How do I know when to increase the weights that I’m lifting?

Answer:
The short answer is: when the current weight starts feeling too easy.

The harder question is defining “too easy.”

If you can comfortably do 15 reps of an exercise with good form, it’s probably time to increase the weight. Personally, I rarely work in the 15-rep range, so for me the signal is usually when I can hit eight solid reps across multiple sets without form breakdown or excessive fatigue.

I also like lifting heavy enough that my heart rate climbs to around 70% of max even during lower-rep sets. If a working set of 3–5 reps feels casual, I know it’s time to move up.

Myth: You have to lift heavy all the time to see strength gains.

Reality:
Muscle growth happens during recovery, not during the workout itself.

The workout is the stimulus. Sleep, food, and recovery are where adaptation actually happens.

Lifting heavy constantly without adequate recovery doesn’t accelerate progress — it stalls it, and eventually reverses it. The technical term is overtraining syndrome, and the symptoms (fatigue, declining performance, elevated resting heart rate, irritability) are easy to dismiss because they look a lot like “just a bad week.”

Strategic deload weeks — lighter weights, higher reps, focus on form — are not a concession to weakness. They’re part of the program.³

The food situation on the Big Island is not especially designed for me.

The local specialties are raw fish, tropical fruit, and rice-heavy plates — and I eat approximately none of those things.

I’ve been surviving on popcorn, macadamia nuts, Caesar salad, and whatever cooked protein I can find that is neither raw nor suspiciously soft.

Sometimes the Radish Fuel Box is aspirational.

This week it’s a dispatch from the field.⁴

As I’m on vacation, I’ll share my current favorite book: Eat Your Ice Cream: Six Simple Rules for a Longer, Healthier Life by Ezekiel J. Emanuel.

I’ll admit it: the title got me. I love ice cream (provided it contains nuts), so an oncologist telling me to eat ice cream immediately had my attention.

But the book is genuinely good. It’s short, practical, and refreshingly unoptimized. The advice is almost aggressively reasonable: have friends, stay active, keep learning, eat decently, sleep enough, don’t be a jerk.

Which, honestly, may be the entire secret.

Excellent beach reading if you happen to find yourself in Hawaii.

Take a deload day.

This week, pick one workout and reduce the weight by 20–30%. Keep your usual sets and reps, but focus entirely on form.

Pay attention to whether your left and right sides are actually moving the same way— take another look at last week's muscle imbalance issue. Notice where you compensate. Notice whether your “normal” training pace has gotten sloppier than you realized.

If you’ve been training hard for more than six weeks without a lighter week, this is not optional. It’s part of the work.

Stay strong,

P.S. The squat rack will still be there when I get home. The ocean has a shorter availability window.
