Gregg Sulkin’s looking pretty hulkin’ these days … and it helps his gym’s wherever he parks his shredded bod.

Gregg hit up a local park in L.A. Monday for a socially-distanced workout. The actor brought the essentials with him … his face mask and these incredible Bowflex adjustable dumbbells that have no doubt helped his arms get absolutely JACKED.

Gregg spent about an hour working out … busting out some bicep curls, bodyweight squats and some push-ups. Unlike some people, dude’s been making the best out of a terrible situation here, working out in makeshift gyms … and the park usually seems to be his place of choice.

Remember … back in May, we saw Gregg busting out another COVID-style workout with a kettlebell and resistance bands. There was also video that showed him and his entire gym essentials. It’s pretty tough to get any of those items right now, ’cause they seem to be sold out everywhere. But, that’s clearly not a problem for Gregg.
