7. You Stray From Your Plan
If you’re just starting out, you may be tempted to try too many things too quickly. You can get overwhelmed and do too much. Set goals and know which muscle groups you want to target before you start your workout.
8. You Ignore Your Limitations
Don’t try to lift more weight than you can handle. You can get hurt, and it can mess up your technique. When you do go for more weight, add only a little at a time and get comfortable with it before going further.
