I'm picking up my old weight bench from my parents' house this weekend and need back brace recommendations. I have a recent history of muscle pulls in my back. Do I just pick up whatever is in the sporting goods aisle at Wal-Mart? Now that I've quit smoking (knock on wood) I'd also like to start running again. I used to run about 30 miles per week and would like to get back up to that pace or better but, alas, have meniscus problems from a skiing incident 15 years ago. I need a knee brace that is supportive laterally but is light and breathes well. Thoughts?
