I really want to get into lifting weights, but I don't really know where to start or what I should be doing. I've seen Caroline Girvan recommended many times and we have a home gym with weights already in it (thanks DH and DSs!), so I'm ready to go, but I just feel like I don't know what exercises to do, how I figure out what weight I should start with, and I guess just how to get started and how to avoid injury.
I'm 52, I run, size 10-12, I have a healthy BMI (22.7), but I'm soft and podgy and not very strong and I would like to tone everything up, get stronger and improve my posture and core strength.
Can anyone give me any advice?
