Sometimes people - especially people over 40 - underestimate what they really are capable of. They believe they're not capable of doing something great. I tell people who are over 40, "I don't want your best. I want better than that. I want better than what you perceive your best is."
Jack LaLanneDo you know how many calories are in butter and cheese and ice cream? Would you get your dog up in the morning for a cup of coffee and a donut?

So many people will just take five pound weights and do something 10 times. What are they getting out of it? Nothing! Say you are going to build up your bank account. If you put in a penny a day, it's going take a long while. It's the same with exercise--the more you put into it the more you take out.
