Horizontal Loading

Horizontal Loading: Performing all sets for a given exercise before moving on to the next exercise. For example, performing a set of dumbbell presses , then resting for 1 - 3 min, then performing dumbbell presses again, resting for 1-3 min, and repeating this sequence until performing all of the sets of dumbbell presses that will be performed, before starting the next exercise. Historically, this has been recommended more often than "vertical loading (a.k.a. circuit training)" for resistance training routines.

• Disadvantage: When optimal rest between sets is performed (2-3+ min), conventional training/horizontal loading can result in very long session durations, or relatively inefficient sessions (load lifted/minute)
• Naming Convention: Note that this naming convention likely originates from training routines documented in tables with the exercises listed in the first column and the repetitions and sets listed in the rows to the right of the exercise.
