Molly Galbraith is done with making New Year's Resolutions to change her body.

When you hear the word ‘fitness‘, what image comes to mind? Chances are it’s someone with a super-svelte figure, thighs that don’t move an inch while running, and a six-pack you could grate a Cherry Ripe on.

Some people do fit into that super-muscly/toned mould. However, it’s easy to forget this isn’t the only form a fit, healthy, happy body can take, and we often cling to the idea that a gym membership and good diet will magically “transform” our bodies in ways that aren’t actually possible.

Molly Galbraith, co-founder of fitness website Girls Gone Strong, understands this all too well. But in 2016, for the first time in as long as she can remember, she’s not making any big resolutions to change the way her body looks.

“This is my body. This not a before picture. This is not an after picture. This just happens to be what my body looks like on a random Tuesday in December of 2015 — it’s a LIFE picture,” Galbraith captioned the photo above, which she posted on Facebook on January 2. It now has almost 100,000 likes, 15,000 shares and 7000+ comments.

The strength and conditioning coach reflected on how freeing it’s been to learn to accept and love her body with all its complexities.

“This is a body that loves protein and vegetables and queso and ice cream. This is a body that loves bent presses and pull-ups and deadlifts and sleep. This is a body that has been abused with fast food and late nights and stress,” she writes.

“This is a body that has been pushed to the brink of leanness in figure competitions and maximum strength in powerlifting meets. This is a body that begged for mercy when it was diagnosed with Hashimoto’s and PCOS.”

There’s probably not a woman alive who hasn’t felt insecure or unhappy about the appearance of her body at some stage of her life. For Galbraith, however, being a personal trainer adds a whole other level of scrutiny.

There seems to be an attitude that PTs should look a certain way — impeccably trim, taut, toned — and if they don't, they're subject to criticism.

"This body has been publicly evaluated, judged, and criticised, and those judgments have been used to determine my level of skill as a coach and a trainer, and my worth as a person, both positively and negatively," Galbraith says.

"Some people say they would 'kill to have this body.' Others say they would 'kill themselves if they had this body.' (Yes, unfortunately that's actually a thing humans say to one another.)" (Post continues after gallery.)

Ultimately, Galbraith says she's spent too much "time, energy and mental" wishing her body would look different, and has come to accept it.

"Today this is a body that is loved, adored, and cherished by the only person whose opinion matters — ME ... This is a kind of freedom I didn’t think I’d ever experience, and it feels really, really good," she writes.

Imagine if all of us felt this way about our bodies? Perhaps that's the only New Year's Resolution worth committing to.
