You don't have to join a gym. Plenty of people get fit and strong without ever setting foot in one. But if you want to, here's how to know you're ready, and where to go next.
The lie
"I'm not ready."
The short version
- You're ready when the home sessions feel easy and you want more.
- Your first gym session: a few machines, light weights, no heroics.
- Nervous is normal. Everyone in there was new once.
Today's rep: Book a gym induction, or decide to keep training at home for another twelve weeks. Jump to it
Ready is a feeling that never turns up
Nobody feels ready. They walk in feeling like it's the wrong wedding.
"I'm not ready" is the last lie, and the sneakiest, because it sounds like modesty. You'll be ready after another month. After you've lost a bit more. After you've bought the proper shorts. After you've watched four more videos about how to adjust a seat on a leg press. Ready is a bus that never comes, and you're stood at the stop in the proper shorts.
Nobody walks into their first gym session feeling ready. They walk in feeling like they've wandered into the wrong wedding. Then they do it anyway. The second time is easier. By the fifth, they're the one who knows where the spray bottles are.
Signs you're ready
Two sets of 12 press-ups, an easy 30-minute walk, and curiosity.
- You can do 2 sets of 12 on the knees or full press-up step.
- A 30-minute brisk walk feels easy.
- You've done most of the twelve weeks, even if some weeks were repeated.
- You're curious about the machines rather than terrified of them. Slightly terrified is fine. Slightly terrified is most of us.
What changes in a gym
More options, smaller steps, and people mostly thinking about their calves.
More options. Weights that go up in small steps. Machines that guide the movement, so they're a good place to start. And people. Most of them are nicer than they look, and all of them are mainly thinking about themselves, their calves, and whether anyone saw them drop that dumbbell.
"Weights will make me bulky"
This one is mostly said by women, usually to a man in a vest who has just recommended deadlifts. It's a lie, but an understandable one, because the internet is full of very big people holding very small dumbbells.
Adult men have roughly 15 to 20 times more testosterone circulating than women.1 That's a big part of why men can build so much more muscle. Women still respond brilliantly to strength training. A review of the research found men and women gain muscle by a similar amount relative to where they started, and women make bigger relative gains in upper-body strength.2 What you get is stronger, more capable, and harder to knock over. Bones get stronger too.3
Bulky takes years of eating and training specifically for it, and often a pharmacy. The steroids page has the honest version. "Toned" is just muscle you can see. You get it the same way everyone does: by lifting things.
Mostly for women
Men, skip ahead. If you're still reading, the next section, about staring, is for you.
The right sports bra
The University of Portsmouth runs a research group that studies nothing but this. In one of their studies, unsupported breasts moved about 15cm during treadmill running, against about 4cm when walking.4 In another, 17 per cent of women said their breasts were a barrier to being active at all.5 The group also reports that most women are wearing the wrong size bra.6
So before your first gym session, especially if it includes running or jumping, get fitted for a proper sports bra. Many shops will do it free. The band should be firm and level all the way round, the straps shouldn't dig in, and nothing should spill out or gap. Then jump on the spot in the changing room. If anything moves that you'd rather didn't, try another.
Feeling watched
Men, don't skip this one. It's partly about you.
"Everyone's looking at me" is mostly a lie. Most people are looking at themselves. But for women it isn't always a lie. In a 2024 survey of 279 women who use gyms, 39 per cent said they felt more intimidated by men when exercising, and most had had at least one unwanted comment from a man.7
Women: go at quieter times for the first few weeks, book an induction, and take a written plan on your phone, so you always know what you're doing next. Headphones are a universal sign for "not now". Some gyms run women-only sessions or areas, so ask. If anyone makes you uncomfortable, tell the staff. A decent gym will deal with it. If it's serious, report it to the police.
Men: don't stare. Don't offer advice nobody asked for, however good your squat is. Give people space, put your weights back, and if someone has headphones in, she isn't looking for a chat. That's it. You'll be in the top half of gym-goers by Tuesday.

Keep the basics
Everything in Bootcamp still applies. You still never miss two.
Everything in Bootcamp still applies in a gym. The Doctor still only speaks once a month. Weekends still count. Rest still matters. "A couple" is still not a number. And you still never miss two.
Your rep for this chapter
Book a gym induction, or decide to keep training at home for another twelve weeks. Either is the right answer if you choose it. "Not ready" isn't one of the options.
