Coaching practices for 90 Minute Work Blocks

Does this sound like the set of challenges you might be facing?
- My day is so chopped into one-hour fragments that I never get the long unbroken stretch where the hard problem finally cracks open
- My most demanding work needs a long uninterrupted stretch to even get going, but it never gets one
- I try to power through a four-hour stretch of work in one go and the back half is garbage I end up redoing
- I pack my day wall-to-wall with back-to-back blocks, and then one task running long knocks the next one back, which knocks the next one back, and by mid-afternoon the whole schedule has collapsed and I’m behind on everything.
- Any meeting I put on the calendar for an hour reliably takes the whole hour even when the actual business is done in twenty minutes
Practices that may help
- Protect at least one half-day maker block per workday
Defend a contiguous 3–4 hour stretch of no-meetings time as a non-negotiable structural element of the week.
Maker vs Manager Schedule - Protect at least one 2–4 hour deep work block daily
Reserve one uninterrupted block per day for your most cognitively demanding priority — at the same time each day.
Ideal Week Design - Structure work in 90-minute cycles
Work in 90-minute focused blocks that mirror the brain’s natural alertness oscillation.
Ultradian Rhythms: Working with Your Brain’s Focus Cycles - Deliberately underschedule your day to prevent expansion cascade
Leave 20–30% of your workday unscheduled as buffer for tasks that expand beyond their box.
Parkinson's Law, Made Practical - Default to shorter meeting lengths
Schedule 25- and 50-minute meetings instead of 30 and 60 — the meeting expands only as far as the slot allows.
Parkinson's Law, Made Practical - Calibrate your personal hyperfocus window length
Find the session length at which your focus quality begins to decline and use that as your block ceiling.
Hyperfocus: Directing Intense Attention to What Matters Most - Block focused work in windows protected from interruptions
Create protected time blocks where interruptions cannot occur — eliminating the source of residue.
Attention Residue: Why Switching Tasks Costs More Than You Think - Day theming
Dedicate whole days to a single domain of work — writing day, meetings day, admin day.
Time Blocking, Made Practical - Work on one task per block to prevent multi-task expansion
Assign each time block a single task — multitasking within a block causes both tasks to expand while neither gets full attention.
Parkinson's Law, Made Practical - Time Blocking, Made Practical
Time blocking means assigning every hour of your day to a specific task on the calendar, so you decide in advance what attention goes where. The core levers — pre-commitment, protecting deep work from shallow work, and confronting how finite your time really is — are well grounded, though the practice demands honest re-planning when reality diverges from the plan.
