have you ever done weight training to increase muscle/strength?
No, but I've been thinking about it - I just lost a lot of weight and my muscles are pretty weak!
weight training is a very good way to improve muscle and health
That's probably what I need to do! Where should I start?
just find a weight training program that works for you and take it slow to build up muscle
Sounds easy enough!  Does this mean I need to actually lift weights like barbells?
 Weight training programs require using free weights and machines for muscle growth
Cool!  What kind of machines?
there are dozens of machines like ab work out, leg press, crunches machines, over head press and so on
Looks like I'll have to get a gym membership then!  I will get one this weekend and will start building my muscles!
