Hey, guys, I had a waterproofing gig for a while where I was constantly digging all day and naturally developed extra ab development and lots of rotational strength, which I absolutely am loving. I found other work recently but wanna make sure my manual labor gains stay with me in a white collar job. Any exercise suggestions to substitute from working a shovel all day? (Addendum: I typically do decline crunches and leg lifts on a pullup bar and call it a day on abs) Thanks guys 👍
