'Be careful of momentum!  Momentum can cause injuries, and is not an effective way to lift weights.',
'Watch out for overtraining. Overtraining can effectively halt any weight loss or sports performance progress you make. Remember to take some time to recover, even if it\'s active recovery.',
'Think nutrition!  Your body will only be as strong as the materials you are building it with. If a staple of your diet is junk food, do not expect to be competing with Olympic athletes.',

'Try a new exercise to stimulate strength gains.  Just slight changes can break a stagnant routine.',
'Periodically reassess and, if necessary, change your goals.  Make sure they are attainable and challenging to keep you on the right track.',
'No pain, no gain.  Avoid this myth.  Pain indicates a problem.  Know the difference between muscle fatigue, which may be uncomfortable, and pain.',
