Why September is the new January: create a sustainable fitness routine that lasts

Discover why now is the best time to reset

Remember the optimistic energy of 1st January?

The clean state.

The new workout gear.

The unshakable belief that this year, things would be different? That you’re going to create a sustainable fitness routine that sticks this time. 

Well, guess what? We're calling it: January is officially so last season.

It’s September. And that means one thing…

The school gates are open, the holiday glow is fading (sorry!), and that 'back to routine' feeling is officially in the air. 

Instead of mourning the end of summer, we're here to tell you why September is actually the best time for a personal reset and creating a workout routine you’ll want to do. 

Forget the bleak mid-winter resolutions; this is when habits are truly born.

The 'back to school' effect

There’s something intrinsically motivating about September, right?

It’s wired into us from an early age: new term, new pens, new diary. 

We like to think this psychological ‘fresh start’ is far more powerful than a New Year's Day hangover. 

You're already naturally shifting gears, making it the perfect moment to slot in new fitness goals. 

Cooler temps, cooler workouts

Let’s be real: battling a heatwave while trying to work out is no one’s idea of fun. (And boy, did we have our fair share of them this year?). 

But with the temperatures cooling, you can now move without melting, which is only a good thing for motivation. 

Plus, it’s still bright and warm enough to take your workouts outside with Mvmnt mobile and tablet. 

So, there you have it: the best of both worlds. 

Goodbye distractions

Summer often brings with it endless social plans, spontaneous trips, and a general 'live-a-little' attitude (which we absolutely love, by the way). 

However, with September well and truly here, those distractions naturally lessen. 

This creates the perfect window for focus. You've got fewer excuses and more mental bandwidth to commit to a solid, sustainable fitness routine. 

Create lasting habits

January resolutions often come with a side of 'all or nothing' mentality. Go hard or go home. Well, that rarely lasts. 

September – with its gentler, more gradual transition – encourages a balanced approach. 

It's about building small, consistent wins that actually stick, rather than burning out by February.
