How I set a weekly exercise goal I actually stick to
I used to set fitness resolutions at the start of the year and quietly abandon them by February. The cycle was embarrassingly predictable: ambitious target, missed week, guilt, give up.
Then I changed one thing. I started building the goal around my actual week, not the version of myself I wished I was on a Sunday night.
This is a casual, slightly messy account of how I landed on a routine I can keep across most of Australia's seasons, whether I'm working from home in Brisbane or travelling for a meeting in Melbourne.
If you're tired of starting over, here's the plain-language system I use, mostly in metric, with a few pointers that work from Adelaide to Perth.
Start with your honest current level
Most goal-setting advice skips this step. It jumps straight to the target.
The trick is to log what you genuinely do for one week, not what you think you do. I used a notes app, but a scrap of paper works too.
For me it was a dog walk around the neighbourhood and one Saturday park run. That was it. Roughly 90 minutes of movement across the whole week.
In Sydney, the harbour path is a free gym, but only if you actually use it. Knowing your starting point stops you from doubling a routine you never had in the first place.
Pick a number you can defend
A defendable number is one you can hit on a bad week, not just a good one.
If a bad week means a work trip to Melbourne and a wedding in Adelaide, your target should survive that. If it doesn't, the target is too high.
I chose three sessions a week, each between 20 and 40 minutes. Any two of those is also a passing grade. Here's how that compares to common alternatives:
| Goal type | Weekly time | Realism | Best for |
|---|---|---|---|
| Three short walks | 150 mins | High | Beginners and returners |
| Two gym sessions | 120 mins | Medium | People with a paid membership |
| Daily 20-min routine | 140 mins | Medium-high | Habit builders |
| One long session plus two short | 180 mins | Low | Experienced only |
Aiming for "more" is not a number. Three sessions is. So is twenty minutes, three times, on a Tuesday, Thursday, and Saturday.
Anchor sessions to existing habits
Habits stick when they're attached to things you already do without thinking.
I do mine after my morning coffee, before I open the laptop. The coffee is the cue, the movement is the automatic response. It took about three weeks before my body just expected it.
In Brisbane, the winter is mild enough that an outdoor circuit in the parklands at 6am feels fine for most of the year, which makes the anchor easier to keep.
The anchor doesn't have to be coffee. It can be the school run, lunch, or the moment you park the car after work. Pick a cue that already exists.
Build in one wildcard slot
Life gets weird. Travel, sick kids, a 38-degree day in Perth where stepping outside feels like punishment.
I keep one wildcard session in my week that I can swap, move, or drop without breaking the streak. It's my pressure valve.
The wildcard is also where I sneak in something different, like the farmers carry movement I picked up from a piece on why you should add more farmers carries to your routine.
Without that flexible slot, my plan would have collapsed by week three of the first month.
Track the streak, not the scale
The number on the scale lies. It lies louder after a long flight from Perth and after a Sunday lunch.
I track the streak instead. How many weeks in a row have I hit at least two of my three sessions? That's the only number I look at.
That simple counter changed everything for me. The goal became "don't break the chain" rather than "lose five kilos by summer".
A streak you can see is a streak you protect. Mine lives on a small whiteboard in the kitchen.
Adjust the target every four weeks
After a month, the body adapts and the mind adapts faster. What felt hard starts to feel boring.
Every four weeks I add something tiny: one more set, five more minutes, or a single new movement to learn. That's enough to feel fresh again.
I also picked up a few intensity tweaks from a weight loss guide I bookmarked last month, which helped me adjust effort without adding time to a busy week.
The four-week review is when I drop anything that isn't working. The whole point is sustainability, not perfection.
Reward yourself with rest days
Rest is not laziness. Rest is the second half of the work, the half most people skip.
I built in two full rest days a week, no guilt attached. On Sundays, the dog and I do a slow walk along Cottesloe Beach and that's the lot.
Rest protects sleep, mood, and the joints, especially if you're doing anything with weights or impact. Skipping it is how injuries start.
Treating rest as part of the plan rather than a failure is probably the single biggest shift in my consistency over the past year.
If I had to leave you with one concrete next step, it would be this: pick one ordinary week, log what you actually do right now, and let that number be your starting line. Everything else follows from there.
