Mike O’Hearn and Joseph Baena Hit Arms

In the video, there were just two exercises hit — dumbbell skull crushers and standing straight bar bicep curls. The workout might have went on longer but the video was kept to a minimum.

Baena began by explaining how he likes to get a full pump to begin arm day.

“So what I usually like to do with the triceps is superset with a little biceps to get the full pump. So you get the stretch, the squeeze on both ends,” Baena said.

The duo began performing skull crushers. Mike O’Hearn completed them first before looking at Baena’s form.

Joseph Baena attacked the workout with curled wrists as the dumbbells are being brought up. This is used instead of using a hammer grip. O’Hearn explained the intensity of this movement and shared his thoughts.

 “I don’t know if you guys see this but to me it looks like he is on stage and he is posing through the exercise. Youngsters go – “Oh, he flexed through the whole exercise? You don’t just lift it?

You’re posing and moving the waist. If he knows it at that age before I knew it at that age, how much better is he gonna be than I ever was.”

Mike O’Hearn closed out the workout with some words of wisdom on how to approach each rep. It is important to focus on the technique of each rep in order to get the bet results.

“You don’t do 12 reps. You do one rep until you get to 12,” O’Hearn said.
