For some of us, walking into a workout with the confidence that we're going to give it our all comes naturally. And quite honestly—going solo is preferred. Who needs those distractions between sets, right? You know what we're talking about—where those rest periods that were slated to be 30 seconds turn into 3:30.

On the other hand—some of us like to work off someone else's energy, or have our intensity or commitment challenged.

Eric and Ryan Johnson, also known as the "Sons of Strength" on Instagram are brothers—and training partners—that thrive off rivalry in the gym. The following program is a 3-day plan that was designed for training partners—or rivals—depending on how you look at it. And 3 days is the perfect amount of time together—no matter how much you love and or hate each other.
