Jay - with all respect, I can't agree with your advice.
Quote:
someone who is starting out should not begin with heavy weights, but should build up the weight over time.
This is exactly the kind of bad "girly" advice that women are given in the magazines and in popular culture. Someone who is beginning to lift should lift as heavy as they comfortably can even just starting out. That doesn't mean they have to start curling 50lbs. For some people "as heavy as they can" may very well be a 3lb weight. Or a 5lb weight. But they shouldn't be AFRAID of the weights. Even starting with 3lbs, you'll gain strength fast. By the end of your 2nd week, you should have moved through the 5lb weights and be into 10lbs. Your body builds strength and adapts that fast.
A good weight lifting rule of thumb when you're starting out is that you should choose a weight where you can just barely complete 3 sets of 10-12 reps. If by the end of your third set you're struggling to lift the weight, you've picked the right weight.
Also keep in mind that you shouldn't use the same weight for every exercise. I can bicep curl a much heavier weight than I can do a tricep curl with. Don't be afraid to pick up various weights and see how they feel when you lift/move them.
That said, FORM is hugely important and if you're going to start lifting weight, then I would strongly recommend paying for at least one session with a trainer just to get the right form. You're much more likely to harm yourself by using the wrong form than by lifting a weight that's too heavy for you.
And finally, with regard to weight lifting, building muscle definition, and building strength, there is no such thing as "toning". Yes, muscle tone as Jay defines it exists ... but that refers to, as she defined ... that state of partial contraction. That simply isn't what most people mean when they say "toned" muscles. They mean developed muscles that show under their skin - the type of muscle definition that makes one look "in shape" and fit.
Also the concept of using very light weights for a gazillion reps to "tone" muscle is simply incorrect. All you're doing is building muscle endurance (and on a very limited level at that). You're not building the kind of muscle that gives you that "fit" look.
There is no such thing as "toning" a muscle with exercise. Either you are building muscle strength and definition or you are not.
Lifting to your limits (and that includes bodyweight resistance and other types of weights) is the ONLY way to build good muscle and to develop that look that most people mistakenly refer to as "toned".
