Don’t persist with exercises, routines or methods that do not help you. If your training has not yielded any progress over the last two months, it is unlikely top yield any progress over the next two months. Make changes!
Training failures are valuable learning experiences that can help you to succeed with subsequent efforts. What could you have done differently that would have improved the outcome? What did you learn that you can put to good use next time? If you approach your training failures and setbacks with a positive attitude, you will use them to increase your chance of success in the future.
Use your gym time wisely. Follow brief but hard training, use exercises suited to you, and strive to add a little more weight every week or two to each exercise. Use a balance programme that includes cardio and stretching. Even if you train well, if you don’t satisfy all the components of recuperation you will not be able to make much, if any progress.
It is amazing how many gym-goers and athletes are negligent with their nutrition and sleep. Everyday you must eat well and sleep well if you want to optimise your recuperation. Do not undermine your training by cutting corners of the gym.
