Back to the gym after years of inactivity.

Without a 'before' picture, and without knowing anything about your routine at the gym other than how often you are going (but for how long? what are you doing there: treadmill? weight lifting? if weights then which program?) it's hard to assess whether you're on the right track or not. Maybe in a couple more months you can post this question again using this picture as a 'before' and adding a new picture as your 'after' or 'progress' shot so others here can assess with more information. Cheers.
