Ask the guys who are doing serious triathlons if there are any limits to what can be done. The limit is right here. You've got to get physically fit between the ears. Muscles don't know anything. They have to be taught.
Jack LaLanneThat is the beautiful part about weights: even if you are 100 year old, you can lift something. Maybe it's only a half a pound or a pound or two pounds. It will still do something.
Jack LaLanneI've never been satisfied with myself, ever. But I feel good about myself, because I'm truthful. I don't corrupt myself. I'm also a perfectionist. I'm very impatient. I've got energy and drive and I can't stand inefficiency in people. And I can't stand dumb people. Why surround yourself with people who are going to tie you down? I don't suffer fools.
Jack LaLanneSometimes 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 LaLanneWhatever you can handle, it's up to you. Pick something where you are going to do it to failure--in other words, where you can hardly do it. That's the key. 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.
