M.E.D. Masterclass #4: Options, Options… and the 4-Day Split

In part 4 of the MED Masterclass, Matt discusses the various ways you can structure the volume and intensity days in the 4-Day Split, including sets, reps, exercise selection, and accessory work. While the 4-Day Split opens up many programming options, the goals for each day of the split are clear: intensity is about setting PR’s (weight on the bar), while volume is about increasing stress via tonnage (sets x reps x weight).

Key Takeaways

Each day has one job. On intensity days the goal is more weight on the bar. On volume days the goal is more tonnage, at a weight heavy enough to keep building strength.

Keep the work the same when you switch. Moving from a three-day plan (HLM or Texas Method) to a four-day split should mean doing about the same total work, spread across four days. If deadlift intensity day was 1×5, start the four-day intensity day at 1×5. If it was 2×3, start at 2×3. Change as few things as possible.

Get enough volume in before you switch. In one coach’s assignment, Matt wanted a top set of five plus back-off sets before the transition, not a single set, because squat and deadlift frequency drops from three times a week to two.

Using the split’s flexibility. Because each lift is trained less often, volume days can add a set or two (3×5 → 4×5 → 5×5). Intensity days keep making small jumps, whether you use triples, a top set of five, or a top set with back-off sets.

Where the split fits. The M.E.D. Masterclass series goes from novice LP to early intermediate programs like HLM or the Texas Method, and then to the four-day split. Matt calls the split “the great wide open” of programming. It’s flexible enough to carry a lifter a long way, but it’s easy to get lost in, so start from what’s already working and change one thing at a time.
