1. Step it up for one month - Commit to adding to your exercise for the next month. Try to commit to exercising every day for the next month and see if you can stick to it. This might breathe some energy into your routine.
2. Add to your routine - If you're bored with your exercise, add something in to spice things up. Use a Bender Ball this month rather than doing plain sit ups. Go swimming rather than running on the treadmill. Find some way to spice up your routine and to add something interesting and new to it.
3. Get a partner - Sometimes, going to the gym with someone else, or playing racket ball with a friend can spice up your exercise routine and add some energy to it. See if you can find someone who wants to get fit with you, and you can enjoy each other's company!
