Easy aerobic volume. Conversational, paced from your VDOT.
In January 2026 I tore my adductor on a threshold run. I am still rehabbing it months later. It finally made me do the maths on what I had been asking of my body: six days a week, double sessions, four on four off with overtime. None of my programming had ever accounted for any of it.
That gap is the whole reason IronShift exists.

Every week IronShift reads what you logged, the sessions, the RPE, the synced activity, and adjusts what is coming. Missed sessions because of overtime and it recalibrates. Ran harder than prescribed and it pulls back the next intensity block.
The sessions movearound the shifts.
Two days, two nights, four off. Eight days, not seven, because your rotation is not a calendar week. Read down the shift tags: the heavy lift and the hard runs never touch, nothing hard lands on the first night or the first day off, and the rest days are programmed rather than left over.
The cycle’s heavy lift. Squat focus plus posterior chain.
First night. The turnaround is protected.
Maintenance press and pull, plus core. Kept medium on short sleep.
First day off pays back the sleep debt. Nothing hard lands here.
The cycle’s one hard run. Recovered, four days clear of the heavy lift.
A full day between the two hardest runs.
The aerobic anchor. Fresh legs, easy pace, last day off.
- 01The heavy lift and the hard runs never touch. Interference is managed session by session.
- 02Nothing hard lands on the first night, and the first day off is for sleep, not a tempo run.
- 03Rest is programmed, not leftover. Five sessions, three real rest days.
Being a shift worker, you never know when you are going to be asked to extend your shift, or come in last minute. IronShift allows you to always get your training done, no matter how hectic your schedule is.
I recently ran a 5k race and smoked my previous PR by almost 90 seconds. That previous time was from ten years ago.
After 20 years of shift work, a lot of gym days were groundhog days. Same exercises, same weights. Now I know exactly what I am doing each day, I can push myself because it logs my previous weights and reps, and I already feel a lot stronger.
Nine weeks into the hypertrophy block and I can see my lifts increasing. It has kept me accountable while staying flexible around my schedule.
That works out to about $8 a month, billed once a year. The standard rate is $14.99 a month and rises as the product earns it. Yours does not.
A direct line to me only works while the group stays small. When the hundred spots are gone they are gone, and the permanent price lock goes with them.
I built IronShift because there was no program that knew I was a first responder working four on four off. Every plan I followed assumed an ideal week I never had, and that assumption cost me a torn adductor and months of rehab I am still working through.
The first hundred founding members are the people who shape what this becomes. The app is live, the trial is free, and the founding rate locks permanently.
