If you are lacking motivation it might be time to find a friend, professional trainer or work colleague to help keep you accountable to your goals. If you make a commitment to exercise with a friend or trainer you are more likely to stick with it and stay on top of your training.
Visual cues are also a very effective method of keeping your goals top of mind - I often find inspiring images and quotes and stick them on my mirror, fridge, car, wherever I am likely to see it the most. Why not try doing this, it's amazing how effective these reminders can be.
Self-visualisation is also an effective way to help motivate you to stick to your goals. See yourself at the end - fit, healthy and happy. These positive self-images will spur you along to get over your lack-of-motivation hump and get active. Once the endorphins kicks in you'll be sure to find motivation, exercising (especially cardio) releases those feel good hormones that give you a natural high.
A good strategy is to define your non-negotiables. For instance, you might not be bothered to complete your eating and exercise diary BUT if you are committed to your goal, make it a NON negotiable that you simply have to do every day before bed! The same goes for exercise. If you define this as a non-negotiable and tell yourself it has to happen, then it will.
When motivation is lacking, let this be your guide to get you through. Now grab a friend and get out there and exercise!!*Disclaimer: Individual results vary based on agreed goals. Click here for details.
