One user said, "I get you, bro, this would be me after one day of shooting " another pointed out, "Only you can you sleep on a desk but I really love you for that."

"Nice one bro flash season 4. You look exhausted. Working so hard. Rest well bro. Keep up the good work. Fans appreciate your hard work. Best Barry Allen," commented a fan.

"Planking Grant Gustin Edition," noted an Instagram user. A self-proclaimed "biggest" fan of Gustin asked, "Is that the CCPD building lift? much excited for season 4 #TheFlash@grantgust #yourbiggestfan."

Previously, Gustin has revealed that fans will see a different Barry, following his return from Speed Force, at San Diego Comic-Con in July. He said, "For Barry it hasn't really been six months. In the Speed Force time is kind nonlinear, and I think this experience in the speed force has been different for him."

"I think when he comes out, he's kind of had this awakening and understanding of things that he's never had before, and he's able to let go of a lot of things," the actor added.

The Flash season 4 returns Tuesday (10 October) at 8pm EST on The CW network.
