Strength Training for Senior: An Instruction Guide for Developing Safe and Effective Programs

I'd recommend the version meant for the end user, however, unless you are actually an instructor. I got both but it was redundant. The core stuff for the weight lifter is in both books. Key thing is that it is very convincing that older folk, those above say 50, can and should do weight lifting. It's a good addition to all the other good stuff you should be doing. This book eases nubie's like myself, into weightlifting, even if we opt to use set equipment rather than free weights. Both free weights and other gym equipment is portrayed in this book.
