Recovery
Sleep is a fat-loss drug (and you're skipping the dose)
Short sleep changes what you lose, how hungry you are and how well you train — at exactly the same calories. It's the cheapest lever in the program.
Time in bed versus time asleep: your seven hours might be six
Sleep efficiency is the gap between when the light goes off and when you're actually asleep. For most people it's costing forty minutes a night.
Active Recovery days are training, not days off
Days 7, 14, 21 and 28 carry a 30-minute session for a reason. What it's actually for, what it definitely isn't for, and why skipping it costs more than skipping a lift.
Training when you're sore: the DOMS decision tree
Soreness is not damage and it isn't a scorecard. Four outcomes — train as written, reduce load, swap to recovery, stop — and the test that tells you which one you're in.
Cold, dark, silent: the bedroom protocol
You can't force yourself to fall asleep. You can remove the four things stopping you — and unlike every other sleep tip, this one is a single evening of work that then runs itself.
Caffeine after 2pm: the half-life argument
A 4pm coffee is still measurably in you at midnight. Here's the arithmetic behind the program's cut-off, and why the people it disrupts most are the ones who swear it doesn't affect them.
Screens 45 minutes before bed: what the evidence supports
Blue light is the part everyone talks about and the smallest part of the problem. The stimulation and the stolen hour are bigger — and they need a different rule.
Sleep debt: can you catch up at the weekend?
Partially. Recovery sleep buys back some of what you lost and leaves the rest outstanding — and the lie-in that pays it has a cost of its own on Monday.
The ten minutes of mobility that keep you training
Four joints limit almost every lift in the program. Here's the drill for each, where it goes in the session, and why general stretching isn't what you need.
Foam rolling: what it does and what it doesn't
Short-term range of motion and how sore you feel: genuine, repeatable, worth ten minutes. Releasing fascia and flushing toxins: not a thing. Here's how to spend the ten minutes.
Niggles vs injuries: when to push and when to stop
Most aches in a training program are green or amber, and stopping for them costs you the month. A small number are red. Here's how to tell them apart in the moment.
Low back pain and the hinge: the fix inside the program
Almost always the last two reps of a set you shouldn't have finished. Here's what goes wrong in a hinge, the two fixes that work, and the substitutions that keep lower-body days running.
Knee pain when squatting: causes and substitutions
Five things to change before you change the exercise — and four substitutions that keep the session's stimulus intact when you have to.
Shoulder health for pressing days
Pressing volume is what irritates shoulders, and the fix is mostly pulling. The ratio that protects them, the three drills before every push session, and the bench variables worth changing.
Stress, cortisol and stalled fat loss: signal vs noise
Cortisol holds water and rewrites your appetite. It does not, on its own, stop you losing fat. Here's the part that's real and the two levers worth pulling mid-program.
Training through a cold: the neck-check rule
Above the neck, below the neck, and fever. A three-way decision that takes ten seconds, plus how to re-enter the plan without trying to buy back the days you lost.
