The 3-3-3 workout rule is being hailed as the ultimate gym split if you want to build strength and muscle, improve cardiovascular fitness and recover properly. As a trainer, I’m often wary of rigid workout routines, but the beauty of this one? There are no real rules to follow outside of the basic workout structure.
The 3-3-3 weekly schedule involves three days of strength training, three days of cardio, then three days of rest and active recovery like gentle walking, cycling, or swimming. It offers structure, is beginner-friendly and prevents overtraining from a lack of rest and recovery.
