This January gym newbie created a few smiles earlier this month while working out at a gym in Las Vegas, Nevada.

She was caught on camera pumping the leg extension machine with her arm.

"I realise that I probably should have helped her out," the filmer wrote online.

"I knew in my gut that my friends wouldn't believe me, so I filmed her instead," he added.

"I had only seen her for about week more in the gym and then never saw her again."

The New Year brings those resolutions that everyone tends to break. On this particular day, January 2, 2017 I had been working out at my gym that I have been a regular at for some time, where it was extra crowded with new faces and people that were unfamiliar with the equipment. While doing my routine, I can see this lady about to exercise directly behind me through the mirror. She sat at a leg extension machine and started to adjust the pad of the machine that your leg goes under to lift, by using the button and hand lever... except she didn't stop. She motioned the lever forward and back again multiple times. I even stood there, staring through the mirror, wondering if she just couldn't get it adjusted properly. I then whipped out my phone and made it look like I was taking a pic of myself through the mirror, but video taped her doing exactly as described above. I realize that I probably should have helped her out, but I knew in my gut that my friends wouldn't believe me, so I filmed her instead. I had only seen her for about week more in the gym and then never saw her again. I still attend this gym.
