LPT: If you're a regular gym-goer who gripes about people who show up just in January, be someone who helps the newcomers.

As someone who is big and also a bit self-conscious about her body and going to the gym, I know I stick to it largely because of the positive attitudes and helpful advice given to me about proper use of the machines in my gym. Newbies are going to feel intimidated already and if they feel like the crowd is groaning about their presence, it will kill their confidence and drive, and they may never get on track.

Give smiles and thumbs up. Take a second to spot a newbie or to correct their form. It makes a difference!
