Fitness does not always have to feel like hard work.
While the after-effects of a tough fitness session - that sense of achievement, accomplishment and progress - are what keep you going back, it is not generally enjoyable in the moment.
Breaking up your usual routine with something different could prove both challenging and refreshing, especially if you have managed to stick to one for the first six weeks of 2021. After all, they do say a change is as good as a holiday.
It could also provide a few laughs for friends and family.
For me recently that has been turning back the clock with some roller skating.
Growing up in the 80s, roller skates were my main mode of transport for a while. Family nights out were to the roller skating rink, neighbourhood kids would converge on our house to power around the carport for hours and Xanadu was one of my favourite movies.
So, when I was sourcing a skateboard for my eight-year-old daughter's Christmas present last year, the roller skate section caught my eye.
A few weeks later, on Christmas Day, I was unwrapping a pair.
It was not an impulse purchase. I pondered it for a few weeks, wondering if you would be able to apply the 'just like riding a bike' adage to roller skates as well as bikes. After all, it had been nearly 30 years since I last roller skated. A lot had changed in that time.
There were helmets and safety gear now, which made me realise I could hurt myself. That was something I never considered as a child. And the first time I got back on - once I finally plucked up the courage - I was thankful to be wearing said helmet.
Luckily, the helmet never came into use because, albeit for a couple of jittery moments, turns out it was just like getting back on a bike.
But what I never noticed before was how many muscles you use while roller skating.
Not only does it require balance, roller skating is a great core, cardio and all-over leg workout. It is also low impact - except of course if you can't stay on your feet - which means less stress on your joints than running.
Not only was it a good workout, it was a fun family workout with the kids, while being active.
And, once I got the hang of it again, it was a lot of fun. Not to mention empowering when I discovered I could still do a "360", although a little less confidently than when I was 11 or 12.
The biggest compliment came from my daughter, who from afar thought I looked "like a teenager".
I had thought I was too old for roller skates but since the purchase I have discovered some other "80s kids" I know also wanting to turn back to clock with a pair. We're already planning some "skating sessions" at local parks, pathways and netball courts as some fun exercise.
A quick internet search also revealed there were devoted roller skating groups and even RollerFit classes where you can learn skating skills and skate in the company of others.
While I have enjoyed a roller skating revival, for others it might be something different. Whatever it is, embrace it and make exercise sometimes seem like it's not exercise to keep refreshed.
