Sibling rivalry is part of being human and that doesn't change just because you're super fit siblings. Jacob Anderson has taken to Instagram to share some EMOM interval workouts and challenging his older brother Alex at the same time. It all started with this workout:

EMOM 10:
10 thrusters (100)
30 double unders

In case you want to try it out, Jacob finished that round in about 38 seconds so keeping your rounds under 40 seconds is key. Like a true older brother, Alex responded with this:

Even Noah Ohlsen got caught in the middle here:

Not to be outdone, Jacob upped the ante:

EMOM 10:
10 thrusters (115)
30 double unders

Jacob is moving at a good clip here because he's still finishing each round in about 38 seconds. Alex Anderson yet again pulls the older brother card:

"That wasn't hard at all" is a classic older brother line. 

Jacob has offered up a new challenge now:
