Daily Undulating Periodisation: Varying the Stimulus Each Session

0 to Elite course · Lesson 67 of 100 · Level 4: Advanced

In lesson 66 you learned block periodisation, where each phase lasts weeks. Daily undulating periodisation, usually shortened to DUP, takes the opposite approach: you train different rep ranges and intensities within the same week, often on the same lift.

What is daily undulating periodisation?

“Undulating” just means going up and down. With DUP, the weight and reps on a lift change from one session to the next. A classic example for the squat over one week:

• Monday, heavy: 5 sets of 3 reps.
• Wednesday, light/volume: 3 sets of 10 reps.
• Friday, medium: 4 sets of 6 reps.

Over the weeks, each of those days progresses on its own track. So you are improving your heavy triples, your sets of 6 and your sets of 10 at the same time. This builds on lesson 51 on rep ranges: different rep ranges train slightly different qualities, and DUP lets you collect the benefits of several in one week.

DUP vs block periodisation

Neither is “better”. They suit different people and situations:

• DUP keeps every quality ticking over all the time. It works well for lifters who get bored easily, who train a lift two or three times a week, and who are not peaking for a specific date.
• Block periodisation (from lesson 66) is better when you need a clear peak on a set day, or when you want to really push one quality.

Many advanced lifters mix the two. For example, they use DUP during the accumulation and transmutation phases, then switch to a short block focused on heavy singles before a test. Lesson 50 on intensity vs volume explains why you cannot push both to the maximum at once, and that rule still applies here.

A sample DUP week

Here is an outline for a four-day lifter focused on squat and bench press:

1. Day 1: squat heavy (5 x 3 at RPE 8), bench medium (4 x 6 at RPE 7), rows and hamstring work.
2. Day 2: bench heavy (5 x 3 at RPE 8), Romanian deadlift (3 x 8), pull-ups, shoulders.
3. Day 3: squat light/volume (3 x 10 at RPE 7), bench light/volume (3 x 10 at RPE 7), arms.
4. Day 4: squat medium (4 x 6 at RPE 7 to 8), deadlift technique sets, core.

Keep the deadlift lighter than the squat in this plan. Most people cannot recover from hard squats and hard deadlifts several times a week, so one main deadlift slot with technique work elsewhere is plenty.

Each week, aim to add a small amount of weight or one rep to each slot, using your training log to track all three tracks separately.

Common DUP mistakes

• Making every day heavy. The light day must stay genuinely lighter, or you lose the recovery benefit and pile up fatigue.
• Poor scheduling. Avoid putting the heavy squat day straight after a hard deadlift day. Plan around what your lower back and legs can handle.
• Changing too many things at once. Keep exercise choice fairly stable so you can see real progress in each rep range.
• Judging a session by the wrong standard. A light day that feels easy is doing its job. Do not compare your sets of 10 with your heavy triples; compare each slot only with itself from previous weeks, ideally at the same RPE.
• Skipping deloads. DUP still needs a deload week every 4 to 8 weeks.

Coach’s note: DUP is a great fit if you train at home or in a busy commercial gym and cannot always predict your sessions, because you can swap the order of days as long as the heavy, medium and light slots all happen. If you would like a programme like this written and adjusted for you, that is what our online coaching is for.

Your action steps

1. Pick one or two main lifts you train at least twice a week to run on DUP.
2. Assign each session a heavy, medium or light slot and write the target sets, reps and RPE for each.
3. Set up three separate progress lines in your log, one per slot.
4. Run it for 4 to 6 weeks, then deload and review which slot progressed best.

Frequently asked questions

What is daily undulating periodisation?

It is a training method where the reps and weight for a lift change from session to session within the same week, for example heavy triples on Monday, sets of 10 on Wednesday and sets of 6 on Friday.

Is DUP better than linear periodisation?

For intermediate and advanced lifters, DUP is often more effective than simply adding weight every session, because it trains several rep ranges and manages fatigue better. Beginners usually progress fine with simpler linear plans.

Can you use DUP for muscle growth?

Yes. Mixing heavy, medium and lighter higher-rep days gives you plenty of quality volume across the week, which is what drives muscle growth.
