The first big question is what do you want to accomplish? This goal has to be SMART -- specific, measurable, actionable, reasonable, and time sensitive. This takes a little more thought than you think. It's not as simple as “I want to get fit.” That is not really SMART at all. Think of something more like “I want to look good by the end of the summer, and to me that means losing 15lbs by August 25th.” This goal is way more real and its reasonable!
There are a lot of reasons why people struggle to reach their strength and fitness goals. These are just a few of the common reasons I see with my clients. These are easy to fix in theory, but need some revisiting over time. Refer back to this list regularly to help make sure you are on track. A lot of time it comes down to your willingness to put the work in, and if you are ready to do what it takes this list if for you.
