This might come across as a "filler" page to some but if you know anything about weightlifting (in particular, why you should always do compound lifts first) you'll get the purpose of showing Walter's routine (and you'll probably see where the plot is going).
I wanted to include some background jokes here with the gymgoers doing wacky shit on the background (you can see the WIP for panel 4 has lots of negative space for that purpose) but the artist Sir has me beat with his end of year fit comics and I don't want to poach on his turf, so I fell back on more "relatable" stuff that I don't remember him poking fun at, like one guy hoarding all the dumbbells without re-racking or people getting visibly impatient while working in.
I'm not super satisfied with the pull-up panel but I think the rest looks pretty good, especially the lunges in panel 3. I picked this subject for the comic to practice more dynamic poses and this page was a good opportunity for that.
