Coming back to mfp after years

Hi guys! Back at MFP after taking a couple years break. I had been staying fit by working at a saw mill until this past february and ive gained 25 lbs and lost muscle mass. My new line of work left me too tired to workout (graveyard shifts) and i kind of became a blob. I do seem to have a good baseline still for muscle mass so thats good. Here are my then and now pics. First is last december. Second is last april to december. And the rest are today. I want to get back to where i used to be.
