The hardest part of any fitness app isn't week one. Week one is easy — you signed up because you wanted to. The hard part is week three, when novelty has worn off and the habit hasn't formed yet.
This guide covers the first fourteen days, with the specific goal of getting you to day fifteen still logging.
Days 1–2: Set up once, properly
Fill in your profile honestly. Your bodyweight, goal, and activity level drive every macro target and workout recommendation you'll see. An optimistic activity level produces calorie targets that quietly sabotage you.
Set your available equipment. If you train at home with dumbbells, say so. The plan adapts, and you avoid the demoralising experience of opening a session that assumes a cable machine.
Pick your five training days. Choose based on your actual week, not your ideal one. If Friday evening is unrealistic, don't schedule it.
Spend fifteen minutes here. Everything downstream — plans, macros, recommendations — is built from these answers.
Days 3–7: Log everything, judge nothing
Your only job in the first week is to record what happened.
- Log every set, including the ones that went badly
- Log meals as you eat them, not at the end of the day from memory
- Weigh yourself at the same time each morning, and expect the number to bounce around
Don't change your diet yet. Don't chase a personal best. You're collecting a baseline, and a baseline built from your ordinary week is far more useful than one built from an unusually disciplined one.
On the first session feeling awkward
It will. You'll be looking up how the logging works mid-set and losing your rhythm. By the third session it's automatic. This is the cost of the first week and it's paid only once.
Days 8–14: Add one change
Now you have data. Pick one thing to adjust — the single highest-leverage change is almost always protein, since most people discover they're 40–50 g short of where they should be.
Other candidates, in rough order of impact:
- Protein intake — get within 10 g of your target, daily
- Sleep consistency — a fixed wake time, seven days a week
- Session completion — finish the sessions you start, even if you cut accessories
- Step count — a floor you hit every day, not an average
Resist changing all four. One change you sustain beats four you abandon by Thursday.
What week two should look like
| Metric | Realistic target |
|---|---|
| Sessions logged | 4 of 5 |
| Days with full meal logs | 5 of 7 |
| Weigh-ins | 5 of 7 |
| Personal bests | Zero, and that's fine |
If you're hitting roughly this, you're doing better than most people at day fourteen — regardless of what the scale says.
The metric that actually predicts success
Not weight lost. Not weight lifted. Sessions logged in a row.
Everything else follows from showing up repeatedly, and showing up repeatedly is a scheduling and friction problem far more than a willpower one. That's why the setup in days 1–2 matters so much: it removes decisions from the moment you're least equipped to make them.
After day fourteen
Once logging is automatic, the interesting part starts — progressive overload, meal prep that runs on rails, and a history long enough to show you real trends.
Start with the five-day split if you're not sure how to structure your week, or work out your protein target if that's your one change for week two.
