What are you struggling with in terms of exercise, if you don't mind me asking? I had a lot of trouble getting into an exercise routine until recently, so I might have some tips, but different people struggle with different things.
Really just following through consistently. Recently I was trying to start out slow and do 30-45 minutes of brisk walking several days per week. I did it for 2 weeks before something came up and I missed a couple of days and I never got back into it.
Until today (yayy) I have been working the graveyard shift at work. I'm going to give it another go with a more sane schedule and focus on being consistent on the times I do go exercise.
