If you can't find the motivation to workout, or if you go through periods of loving it, and then periods of being totally unmotivated, your answer could lie in just a few small adjustments. Here are some unconventional ways to motivate yourself again.
Music Matters: Music really is a motivator. You don't think that when you aren't listening to it, but if you're at work and debating on working out, put on a motivational or meaningful song and force yourself to listen to it and let your mind wander to (hopefully) ambitious thoughts.
Buy new workout clothes. Materialistic? Maybe. But, it might work for you. Whenever I get a new pair of shoes, I always get really excited to run. Buying new technology could also help you get back in the swing. Subconsciously, I think it holds you accountable. And it makes you guilty if you don't use it.
Fill your social media feeds with workout motivation. Visuals specifically. Seeing and hearing motivation can wake up your senses and in turn, fire up your motivation. Most of us are on these mediums all day, so why not do ourselves a favor and try it?
Signing up for a race or a goal. Pay money. No one enjoys wasting money, and then you feel twice as guilty about not working out when you waste it on NOT WORKING OUT. Sign up for an event, or even just a class. Hold yourself accountable.
