I've bitten the bullet and joined a gym. I'm scared and nervous but in my last year of my 50s I really want to take more care of my health. I've had a few health issues over the last 5 years that have knocked my confidence, so it's about time I got it back.
So, my question to all you lovely gym goers is about gym etiquette. What are the do's and don'ts in the gym. I don't want to a) make a fool of myself and b) piss regulars off.
I would also be really grateful for advice on exercises to help (gently) with upper body strength. I've had a bilateral mastectomy and various other bits of surgery over the last few years, along with a shoulder prone to dislocation so I'm a tad worried about that.
Thank you!
