How to start gym training

The short version: two or three workouts a week, your whole body each time, a few sets per exercise with weights that feel hard by the last reps, and a little more whenever it starts to feel easy.

That's what Chango plans for you when you start, and below is why, and what the research says.

You don't need to become an expert first

Search for "how to start at the gym" and you'll find a hundred programs, each one sure it's the right one. Chango was made on a simple idea: you shouldn't need to know what to do at the gym. You tell Chango how often you'd like to train and how much time you have, and every workout is ready when you get there. Here's what's behind the plan.

Why two or three workouts a week, whole body each time

Guidelines recommend strength training on at least two days a week for adults [1]. Research on muscle growth points the same way: training each muscle twice a week builds more muscle than training it once, with the same total amount of work [2].

So when you choose one to three workouts a week, Chango trains your whole body every time. Each muscle gets work at least twice a week, and you never have to think about which day is for what. If you train more often, Chango splits the work automatically.

Why rest is part of the plan

Muscles get stronger between workouts, not during them. Research recommends about 48 hours of rest before training the same muscles hard again [3], and a hard workout needs a little more.

That's why Chango follows the recovery of every muscle and picks the ones that are ready. You don't need to remember what you did on Monday: if your legs are still recovering, Chango leaves them alone and trains something else. The Recovery view shows at a glance which muscles are ready and which still need time. And if you add an exercise for a muscle that hasn't recovered yet, it shows in red as Overloaded in your workout, before you do it. Chango doesn't plan workouts that push a tired muscle too far: a muscle that hasn't recovered lifts less, so you'd work harder for less.

Why 8–12 reps, and why it should feel hard

For people starting out, research recommends sets of about 8 to 12 reps with a weight that makes the last reps hard [3]. How close you get to your limit matters: the closer to failure a set is taken, the more muscle it builds [4].

You don't need to guess the right weight. Every set already has a planned effort, so if it felt as planned, you don't need to do anything. Only if a set felt harder or easier, you change the effort, from 1 to 10, and Chango adjusts the next set right away: a bit lighter if it was too much, a bit heavier if it was easy. Within a few workouts, the weights fit you.

Why the weight goes up little by little

Getting stronger means asking a little more of your muscles over time. Research calls this progressive overload and recommends raising the load in small steps once you can do more reps than planned [3].

Chango does this for you. First your reps go up, and when you reach the top of your range in every set, Chango adds the smallest step of weight next time. You just lift what the app shows.

Why the warm-up is a light set

Research shows the clearest benefit from a warm-up set of the same exercise with a lighter weight, while the benefit of general warm-ups like cycling is unclear [5]. A few minutes on a bike is fine, but you don't need it.

That's why Chango starts your heavier exercises with a warm-up set already in the plan.

Why the rest between sets is longer than you'd think

It's tempting to rush, but longer rests let you lift more in the next set. In research, people who rested 3 minutes between sets gained more strength and muscle than those who rested 1 minute [6].

Chango sets your rest by the exercise: 3 minutes after heavy lifts, 2 minutes after other big ones and 90 seconds after smaller ones. The timer runs on your screen and even on your lock screen, so you can sit down and let it count.

What you'll notice

You'll probably feel stronger surprisingly fast. In the first weeks your body learns the movements, and the weights go up quickly. Your muscles may feel sore for a few days after the first workouts. That's normal, and it fades as your body gets used to training.

And you'll see it build up. After every workout, the muscles you trained light up on your own 3D figure. Turn it around and look back over your week, your month or your whole year. That's where you see what really makes the difference: not one perfect workout, but showing up, week after week.
