1. Know why you are training. Without having specific goals, its hard to have motivation. Is there a race that you are doing next summer? What is your goal for the race?
2. Create a positive affirmation. Or two. These don't have to be true now but they should be things that you want to be true. So maybe you don't currently like getting out of bed to train but if you want to, you could have an affirmation that says "I like how I feel during the day when I workout first thing in the morning." Tell yourself this and in the future you may find that it is true!
More thoughts down the road but these should help you get started. I know I'll be up first thing in the morning and on the bike in the basement. I've got some Netflix to catch up on and a duathlon in April to train for!
