I Dropped From 5 Training Days to 3 and My Testosterone Went Up – The Data

I trained five days a week for three years and my testosterone went nowhere useful. I dropped to three days a week and my T went up 140 ng/dL in four months. I’m a personal trainer. This embarrassed me.

TL;DR: I was overtraining and calling it dedication. Every marker that mattered – testosterone, free T, HRV, recovery – moved in the right direction when I cut training days. Here’s the full data, the protocol shift, and the thing I now tell every client who comes in training six days a week.

Why I Started Tracking

I’m Tyler Prescott. I’m 29, I own a small strength gym in Denver, I played D-II linebacker in college, and I’ve been lifting seriously since I was 18. I know more about training program design than most people you’ll meet. That knowledge did not stop me from making the most common mistake in the sport.

At 26, my body composition started getting worse despite training harder. I was running five days a week – upper/lower split plus an extra conditioning day. Eating clean. Sleeping “enough” (I thought). And my body was slowly getting softer, my strength gains had stalled for months, and I was tired in a way that didn’t feel normal anymore.

I Googled “why is my testosterone probably low” around 2 AM one night. Found Ron Males’ content on PowerandBulk.com. The piece that stopped me was the one on training volume as a hormonal variable. The idea that training more was making things worse had genuinely never occurred to me in a practical sense. I knew it existed theoretically. I’d never applied it to myself.

I got bloodwork done for the first time in my adult life. The numbers were humbling.

The Baseline – Month 0

Bloodwork Marker	My Numbers	Where I Wanted to Be
Total testosterone	488 ng/dL	650-800 ng/dL for my age
Free testosterone	11.4 pg/mL	18-25 pg/mL
SHBG	41 nmol/L	20-40 nmol/L (high-normal)
LH	3.4 mIU/mL	3-8 mIU/mL (low-normal)
Cortisol (AM)	22 mcg/dL	10-18 mcg/dL (elevated)
Estradiol	26 pg/mL	20-30 pg/mL (fine)

Training data at the same time:

• Deadlift working sets: 465 lbs x 3
• Back squat: 405 lbs x 3
• Bench press: 295 lbs x 5
• Training days per week: 5
• Average session length: 75-90 minutes

488 ng/dL at 28 years old training five hard days a week is not good. For context, I was putting in more training stress than most men twice my age, and my T was 100+ points below where it should be for a lean, active 28-year-old.

The morning cortisol at 22 mcg/dL was the tell. That’s elevated. (The HPA axis – hypothalamic-pituitary-adrenal system – was running chronically elevated cortisol, which directly suppresses GnRH production at the hypothalamus and blunts the testosterone signaling cascade downstream). My body was treating my training as a chronic stressor it couldn’t recover from, not as an anabolic stimulus.

I called Ron. His first question: “How many days are you sleeping more than 7.5 hours?” Answer: two, maybe three nights a week. His second question: “When did you last take a full week off?” Answer: I couldn’t remember.

He told me the same thing he tells a lot of people who think they’re being disciplined: “You’re not recovering. You’re just not stopping.”

The Protocol Change

We cut from five days to three. Monday, Wednesday, Friday. Full-body strength focus. The 6-12-25 Method Ron uses became the core structure – which was new to me despite having been programming clients for years. The tri-set approach of a heavy compound at 6 reps, a moderate compound at 12, and a high-rep isolation movement at 25 in sequence sounds straightforward until you actually run it and realize what it does to your lactate threshold and the anabolic hormonal response mid-session. I had clients on this structure before I’d ever run it myself, which was embarrassing in retrospect.

Three session structure:

• Day A: Trap bar deadlift (6) / Romanian deadlift (12) / leg curl (25), followed by overhead press (6) / dumbbell press (12) / lateral raise (25)
• Day B: Back squat (6) / Bulgarian split squat (12) / step-up (25), followed by weighted pull-up (6) / chest-supported row (12) / face pull (25)
• Day C: Bench press (6) / incline dumbbell (12) / cable fly (25), followed by Romanian deadlift (6) / hip thrust (12) / hamstring curl (25)

Sessions ran 55-65 minutes. I had to fight the urge to add accessory work every single session for the first three weeks. Ron’s framing helped: “The program isn’t working despite the reduced volume. It’s working because of it. The extra work you want to add is the thing that was killing your recovery.”

Sleep changed immediately. Going from five training days to three meant my nervous system wasn’t in a perpetual recovery deficit. Within two weeks I was consistently hitting 7.5-8 hours. Within a month I was waking up before my alarm for the first time in years.

Month 2 Check-In

Marker	Month 0	Month 2	Change
Total testosterone	488 ng/dL	572 ng/dL	+84 (+17%)
Free testosterone	11.4 pg/mL	15.2 pg/mL	+3.8 (+33%)
SHBG	41 nmol/L	38 nmol/L	-3
Cortisol (AM)	22 mcg/dL	16 mcg/dL	-6 (-27%)
LH	3.4 mIU/mL	5.1 mIU/mL	+1.7

Training numbers at 8 weeks:

• Deadlift working sets: 495 lbs x 3 (up 30 lbs)
• Back squat: 425 lbs x 3 (up 20 lbs)
• Bench press: 315 lbs x 5 (up 20 lbs)

I added 30 lbs to my deadlift in eight weeks training three days a week instead of five. My strength went up while my training volume went down. My T went up. My cortisol dropped significantly. And I felt better in the gym on each session than I had in years – because I was actually recovered when I walked in.

My training partner Dan had been skeptical of the whole experiment. He watched me pull 495 at the 8-week mark and texted me afterward: “What the hell did you do differently.” I told him. He didn’t believe volume reduction was the answer. He started running the same experiment two weeks later.

Month 4 – Final Results

Marker	Month 0	Month 2	Month 4	Change (4mo)
Total testosterone	488 ng/dL	572 ng/dL	628 ng/dL	+140 (+29%)
Free testosterone	11.4 pg/mL	15.2 pg/mL	19.8 pg/mL	+8.4 (+74%)
SHBG	41 nmol/L	38 nmol/L	34 nmol/L	-7
Cortisol (AM)	22 mcg/dL	16 mcg/dL	12 mcg/dL	-10 (-45%)
LH	3.4 mIU/mL	5.1 mIU/mL	6.4 mIU/mL	+3.0
Estradiol	26 pg/mL	25 pg/mL	22 pg/mL	-4

Strength at four months:

• Deadlift: 515 lbs x 3 (up 50 lbs from month 0)
• Back squat: 445 lbs x 3 (up 40 lbs)
• Bench press: 335 lbs x 3 (up 40 lbs from a 5-rep weight)

Body composition shifted visibly – leaner with more muscle definition – without any meaningful diet change. The improved testosterone and reduced cortisol shifted the hormonal environment toward anabolism. (Supercompensation – the adaptation process where the body rebuilds stronger than before after a training stress, which only happens with adequate recovery time between sessions) was finally actually occurring instead of being short-circuited by the next training session before it could complete.

628 ng/dL at 29 from 488 at 28. That’s where I should have been all along. The five-day training week was the thing standing in the way of it.

Why This Happens – The Mechanism

Training is a hormonal stimulus. The acute testosterone spike you get from heavy compound movements – squats, deadlifts, the big pressing and pulling patterns – is real and documented. The problem is that this acute response requires adequate recovery to translate into a chronic improvement in baseline T. If you’re training again before that recovery is complete, you’re stimulating the system before it’s reset.

More concretely: chronic high training volume without adequate recovery elevates cortisol persistently. Persistent cortisol elevation directly suppresses the GnRH signal from the hypothalamus and the LH signal from the pituitary. Testosterone production drops. You’re generating the stress response faster than the anabolic response can follow. The mechanism behind heavy compounds and hormones is real – but it only works if recovery is sufficient for supercompensation to complete.

The 6-12-25 Method exploits this intelligently by stacking the acute hormonal stimuli within a session – the heavy compound fires the acute testosterone response, the moderate movement extends the time under tension for hypertrophy, the high-rep isolation finisher pushes into the lactate threshold that amplifies the GH response. Three distinct signals, one session, 55-65 minutes. Ron’s position is that this structure within a session makes three hard days a week outperform five sloppy ones on the hormonal response side, and my four-month data supports that.

What I Now Tell My Clients

I program almost all of my clients for three strength days a week now. The resistance I get is predictable – “only three days, isn’t that not enough?” – and my answer is consistent: three days where you’re recovered and can push intensity is more productive than five days where you’re grinding through sessions in a cumulative deficit.

The signs I look for that tell me someone needs to cut training frequency:

• Strength numbers that haven’t moved in more than 6-8 weeks despite consistent training
• Body composition getting worse despite training more
• Waking up tired even after “enough” sleep
• Dread before training sessions – not normal pre-workout nerves, but genuine reluctance
• Resting HR trending upward over weeks

All five were present in my own baseline data. I’d trained around them for two years.

The Protocol That Actually Worked

Tier 1 – Non-Negotiables (biggest impact)

• Cut to three strength days per week if you’re doing five or more
• Sessions 55-65 minutes maximum – not 90
• Sleep 7.5-8.5 hours on non-negotiable schedule – this is the recovery that makes the three days work
• Get bloodwork before starting so you have a baseline to compare

Tier 2 – Add After Week 4

• Foundation supplement stack: zinc picolinate 25mg, vitamin D3 5,000 IU with K2, magnesium glycinate 400mg before bed
• Structured 6-12-25 tri-sets for the primary compound movements – not just random set-rep schemes
• Progressive overload tracked weekly – if you’re not beating a number from last week, you’re not recovering

Tier 3 – Once Tiers 1 and 2 Are Locked

• HRV tracking to confirm recovery is actually happening between sessions
• Second bloodwork panel at 8-10 weeks to see what moved
• Diet dial-in once the training stress and recovery are calibrated

Tier 4 – Skip These Until You’ve Addressed Volume

• Testosterone boosters or adaptogens if you haven’t fixed the training stress first
• Adding conditioning days on top of a high-volume program
• Switching programs every 4-6 weeks (the problem isn’t the program, it’s the recovery)

Before You Ask

Won’t I lose muscle training only three days?

I gained 50 lbs on my deadlift in four months training three days. Dan, my training partner who ran the same experiment, gained 35 lbs on his squat in three months. Muscle responds to sufficient stimulus plus adequate recovery. Three well-structured days provides sufficient stimulus. Five under-recovered days does not provide adequate recovery. The math goes the other way than most people assume.

What about cardio and conditioning?

Walking works and doesn’t compete with recovery. I do 20-30 minute walks most days – not structured cardio sessions, just movement. Ron covers the cortisol management angle on low-intensity movement in the cortisol and testosterone article. High-intensity conditioning on top of three strength days is a different conversation and one I’d only have once recovery markers are confirmed solid.

How long before I see results?

My HRV started moving in week two. Sleep quality improved in week one. Strength started moving at week six. T panel at week eight showed meaningful change. The nervous system recovery happens fastest; the bloodwork follows over weeks and months. You need at least 8 weeks before judging whether it worked.

I’m not a strength athlete. Does this apply to me?

If you’re training more than four days a week and your progress has stalled, the recovery math is almost certainly part of the problem. The three-day principle isn’t about being a powerlifter. It’s about providing enough recovery for the hormonal and structural adaptations to complete before you stress the system again. That applies regardless of training style.

The Honest Takeaway

Ron’s been the older brother in fitness I never had. The concept that training less could move my T up 140 points was something I would have dismissed two years ago. The data didn’t let me dismiss it.

I was 28 years old, a certified personal trainer, training five days a week, and my testosterone was 488 ng/dL. The training wasn’t the solution to the problem. For two years, the training was the problem.

Three days a week. Full recovery between sessions. Progressive overload on the big compound movements. Give your system a chance to actually adapt to what you’re doing to it.

The program doesn’t change every month. The recovery does.
