Speediance V3 improves the interface and key workout controls, but the update also shows where Speediance still struggles to turn strong hardware into a polished family training platform.
Leer análisis completo →
Speediance V3 did not remove Partner Mode entirely, but it did lose the old Free Lift version that made the hardware feel uniquely flexible. I tested the older V2 mode with my daughter to see what was fun, what was broken, and what Speediance should rebuild.

Mike Israetel’s roll with Johnny Shreve drew criticism for looking slow, but time-to-submission misses the point. In a filmed, friendly training round, intent changes everything.
Leer análisis completo →
A tournament match became a personal audit of skill, composure, and belief. Under fatigue and pressure, the question was not just whether he could win, but whether his game truly held up.
Leer análisis completo →
Not every fast promotion is fake, and not every slow promotion is noble. In BJJ, belts get messy when skill, loyalty, politics, money, and gym culture all collide.

If champions, executives, and everyday hobbyists can step onto the competition mat in their 40s and beyond, age is not the real barrier. The harder question is whether you are willing to test yourself honestly.

After extensive real-world use, the differences between the Speediance 2S and the original come into focus in ways spec sheets never show. This review breaks down the practical upgrades, quirks, and buying tradeoffs that matter most.
Leer análisis completo →
This six-month transformation wasn’t built on hype or shortcuts. It came from honesty, consistency, and finally facing the habits that had quietly taken over.
Leer análisis completo →
Big transformation stories usually leave something out. This one is about what dramatic change really demands—and why the full context matters more than the before-and-after photo.

After being locked out of Claude Pro for three days with no access, I tried to exercise the refund option Anthropic explicitly promised in their email. That's when I discovered their 'refund policy' is designed to ensure you can never actually get your money back — and they won't even prorate the days they locked you out.

WHOOP's health age metric gave me a shocking reality check after a month of vacations and zero training. I'd managed to get my WHOOP age younger than my actual age last year-but one month of detraining reversed all of that progress and then some.

Vacations, travel, life - I went a full month without real training. The Garmin scale's health age feature told me what my body already knew. Here's what actually happens when you detrain.

When I was hospitalized with a serious health condition, I'm 99% sure the fact that I didn't die or need emergency surgery was because of all those years of running. Here's what the data actually shows.

The V3 software update removed partner mode from Freelift, introduced a dead button on Toby's 2S, and changed the UX. Here's what's better, what's broken, and who Speediance is actually not for.
Leer análisis completo →
The body battery is noise. The sleep tracking is calibrating. The stress meter is useless. So why is the Garmin still on my wrist every single day? Because the things it does well, it does better than anything else.
Leer análisis completo →
Toby breaks down why he sticks with Garmin for running despite questioning its metrics - covering the hardware, ecosystem, and the features that actually matter to him.
Leer análisis completo →
Speediance accidentally removed one of their most impressive features — a freelift partner mode with independent weight tracking per side that was in all their early demos. My daughter Lily and I demo it on V2 software before it's gone forever.
Leer análisis completo →
The V3 software update removed a partner mode that was literally in all of Speediance's original demo videos. I demo it with my daughter Lily on the V2 machine and explain why the feature was better than what Tonal offers - and why it's still missing in V3.1.
Leer análisis completo →
The Free Lift partner mode that let two people lift different weights simultaneously is gone in V3 software. It was in all their original demos. It did something Tonal can't. But here's why it didn't actually work - and why I'm not upset it's gone.

I wear a Garmin 265S and a WHOOP 5.0 simultaneously. They serve completely different functions — one tells me what I did, the other tells me how well I recovered. Conflating them is how people make bad training decisions.

After years of Push Pull Legs and full body workouts, I landed on a full body minus legs approach that fits my life. Here's why it works, when I switch to bro splits, and what I learned from the Lunar Challenge.
Leer análisis completo →
I built my physique with Push-Pull-Legs. Now I do full body minus legs and lift 41,500 lbs per session. Here's exactly why I made the switch, what changed in my programming, and why the Lunar Challenge forced me to reinvent my training split mid-stream.

Toby compares Whoop and Garmin wearables for BJJ and strength training, covering comfort, features, battery life, and why he switched from Apple Watch.
Leer análisis completo →
I've worn both simultaneously for over a year - including on the mat. The WHOOP 5's form factor 'improvements' are a scam, Garmin's bicep strap is a myth for BJJ, and the real answer is knowing which device to trust for which question.
Leer análisis completo →
One failed bench rep bent my bar nearly in half and could have ended far worse. This is the real story, the safety lesson, and why training alone with free weights deserves more respect.

After years of trying every split imaginable, here's what actually works—from the grueling Arnold Blueprint that built my physique to the full-body workouts I do today. The answer might surprise you.
Leer análisis completo →
I used Arnold Blueprint PPL to go from 250 to 180 pounds. Now I do full body minus legs. Here's exactly why the training that gets you there isn't the training that keeps you there.

Every reviewer says WHOOP 5 is smaller. They're repeating the company line. Here's the actual measurements - and why the new design feels intentionally malicious.

Toby weighs in on whether competition should be mandatory for black belt promotions in BJJ, defending Mike Israetel's belt while calling out critics who've never rolled.
Leer análisis completo →
Ever wonder why some BJJ students fly through belt promotions while others seem stuck for years? Toby breaks down the unspoken rules of Jiu-Jitsu grading, from gym politics to competitor advantages, and shares his own experience getting promoted at a slower pace.
Leer análisis completo →
I took third at my last tournament with a reverse triangle - and it made me realize jiu-jitsu has a belt promotion problem. Here's why requiring tournaments for black belt might be fair, and why it also might not be.
Leer análisis completo →
Black belt mills exist. Derek Moneyberg got one in 3 years without competing. Mike Israetel got one in 10 years and people say it's fake. Only one of those criticisms is fair.

Greg Doucette criticized Mike Israetel for taking 3.5 minutes to submit Johnny Shreve. Here's why that critique is garbage - and what rolling for entertainment actually looks like.

A near-miss with a neck submission in BJJ revealed a terrifying reality: sometimes the risk isn't the technique itself, but what happens when your opponent's weight comes down on the wrong part of your body at the wrong moment.

Everyone's calling Mike Israetel's black belt fake. I was there when he was a brown belt. I've rolled with his students. Here's my take as a brown belt who's actually been on the mat.

I went from 242 to 188 lbs in six months in 2023. Someone commented they wanted my physique so they could buy a Speediance. I owe them honesty: here's every drug, every protocol, every data point. Nothing natural about it - and I'm not pretending otherwise.
Leer análisis completo →
I went from 242 pounds to 188 pounds in six months. But I've never done it naturally - not in high school, not in 2023, not once. Here's exactly what I used, why I'm transparent about it, and whether you should try to replicate this.

There's a sequence button on Speediance that most people ignore. Here's how to use it to build workouts faster - and why I use Stamina mode for everything now.

The Speediance eccentric setting is the most underrated feature on the entire machine. Here's exactly how I use it - and why it protects your joints while building more muscle.

Skip the Customize option for warmups - here's exactly how to use Stamina mode to create the perfect warmup set that won't reset your 1RM or break your workout settings.
Leer análisis completo →
Don't touch the Customize option on Speediance. I'm dead serious. Here's what happened when I accidentally broke my settings across every exercise - and why the 20 and 13 rep formula is the only setup you need.
Leer análisis completo →
Lily joined me for a Speediance session - lat pulldowns, bicep curls, rows. She crushed 10 reps at 8 lbs and taught me something about why kids should lift early.

Spotter Mode 1 is useless. Spotter Mode 2 creates real drop sets. But after filming the demo, I realized why I don't use either one - and why you probably shouldn't either.
Leer análisis completo →
Spotter Mode 1 vs Spotter Mode 2 work completely differently - and using the wrong one for drop sets is a recipe for disaster. Here's what you need to know before trying this at home.

A deep dive into the Speediance Gym Monster 2S dynamic weight modes and how to use them correctly for optimal training.
Leer análisis completo →
A direct side-by-side feel test suggests Speediance's 40 lb setting tracks closer to dumbbell reality, while Tonal's 40 lb can feel dramatically heavier due to calibration differences.

I pushed the Speediance 2S to its absolute limits with a 260 lb lat pulldown test. Would the machine hold up or snap? The results shocked me.
Leer análisis completo →
Someone posted that their lat pulldown felt wobbly at high weight. I'd never even thought to test 260 lbs on this thing. So I put on two weighted vests, grabbed the max resistance - and the machine sent me up the wall.
Leer análisis completo →
At 200 lbs body weight, I needed two weighted vests (nearly 300 lbs total) to even attempt a 260 lb lat pulldown. The machine didn't budge. The cables didn't wobble. Here's what this machine is actually capable of - and why the max weight test revealed everything.

The default Speediance setting is wrong. Here's why Unlimited Sets should be on and how it fixes your progressive overload.
Leer análisis completo →
Unlimited Sets is off by default. That's the wrong default - and it's why people underload every workout. Then there's eccentric mode, which changes the entire lift. Here's exactly how I have mine set up after 1.2 million pounds.

Paul Sklar told his audience they could turn off their Tonal membership and still use custom workouts. That's a lie. Here's what you actually get when you stop paying - and why every positive Tonal review comes from a unit where Tonal pays the membership.

The 2S is nearly silent in standby mode. The original sounds like a late 90s gaming PC. And that extra 40 pounds of resistance? It feels like 60. Here's my unfiltered first look after getting both machines home.

Tonal the device helped me transform my body and lift over 9 million pounds. Tonal the company? Price hikes, terrible support, and membership lockouts make it one of the worst ownership experiences I've had.
