Negativity can get you down and when you are making a valiant attempt to make healthy changes to your life, it can also slow you down and create an uphill struggle. Of course, you can simply try and battle your way through the negative obstacles in your way but you might save energy and get further if you confidently and proactively find ways to deflect negativity successfully!
You don't have to bounce around with a big grin on your face every time you work out - although with us we wouldn't blame you! - but you do need to keep motivation levels up and this means feeling positive about what you can achieve and how you are going about it.
