Many people are reluctant to lift heavy weights or to do certain exercises because they think they will get injured.

Considering a weight to be "too heavy" or fearing it will hurt you is the wrong approach.

Avoiding a certain exercise because you think it is dangerous is the wrong approach.

A weight is too heavy only if you are not prepared to lift it and an exercise is only dangerous if you are willing to perform it incorrectly.

Weight training is simple, really. All you are doing is training your body to move against a load. The load you are trying to move constantly resists your efforts to move it. If you are strong enough to apply more force to the object than it exerts upon you, then you will move it. Overcoming the load is what builds strength, coordination, better-looking muscles, stronger bones, and much more.

As simple as weight training is, it is not, and should not be easy. If you are training with a weight that is easy to move, you really are wasting your time. The weight should be fighting against you. If it feels like you are just taking the weight along for a ride, you need to use a heavier weight.

You should at times feel like the weight is barely moving.

You should at times feel like you are beginning to break form.

When these things happen is about the time many people think they're on the verge of getting hurt. In actuality, this indicates they are beginning to work with sufficient weight. This is the kind of weight required to elicit the positive adaptations associated with weight training.

In order to lift weights safely, your body must get into and hold the correct positions, brace, and engage different muscles at certain times. Do these things effectively and there should be no limit to the amount of weight you can lift or the types of funky looking exercises you can do. Fail to do these things and yes, you will likely get hurt.

Lifting 200 pounds isn't going to hurt you. Your unpreparedness to lift 200 pounds is what is going to hurt you.
