You don’t have to hire a
personal trainer to start a new exercise program, but it’s important to
realize that there is a science to each of your favorite
strength-training moves. As a trainer, I see many people depend on their
own knowledge and very few professional resources to guide them, and
these are the most common mistakes I’ve watched people make. When
performing these 10 strength-training exercises, the main thing to keep
in mind is that the beginning of all movement starts with the core. By
engaging your core, these exercises can be executed with more
stabilization, power and strength.
