Hybrid training
Running and strength training in one plan.
Most people run and lift on two separate plans that were never told about each other, then wonder why their legs are dead on the run and their squats stall. The two do not have to fight: they just have to be sequenced. FitBoost plans them in the same week instead of two plans colliding.

| Mon | Easy run | Conversational pace |
|---|---|---|
| Tue | Upper body | Push and pull, barely interferes with running |
| Wed | Tempo run | 20–30 min at a comfortably hard pace |
| Thu | Rest | Recovery is part of the plan |
| Fri | Lower body | Squats, hinges, single leg, placed away from your hard run |
| Sat | Rest | Recovery is part of the plan |
| Sun | Long run | The session the race depends on |
Why this week is shaped like this
- The long run is protected from accumulated lower-body fatigue, nothing heavy lands the day before it.
- Strength is distributed across the week rather than clustered around key runs: lower body sits furthest from your hard days, and upper body takes the awkward slot because it interferes least.
- Quality running is separated from lower-body strength where possible, and kept clear of the long run so neither arrives tired.
- Rest days are part of the plan, not the days you failed to train.
Weeks 2 to 12
Week 1 is above. The rest is the part that makes it a plan.
Want this to adapt every week?
The week above is a fixed template, a good one, but it repeats forever. What FitBoost adds is everything after it: volume that grows from what you actually absorbed rather than a flat percentage, a long run that stays the longest run, deloads triggered by accumulated load instead of the calendar, and strength that moves when a run turns out harder than planned.
Those numbers are different for every runner, which is why they are not on this page.

Combine them by keeping hard days apart, running before you lift on the same day, and putting heavy leg work as far from your hard run as possible. FitBoost plans both in one week so you do not have to sequence it yourself.
Why they interfere
Hard running and heavy lifting draw on the same legs and the same recovery. Do them badly spaced and each one arrives at the other while you are still repairing, you get the fatigue of both and the adaptation of neither.
This is not a reason to drop one. It is a reason to put them in a deliberate order.
The rules that actually matter
If you want to sequence it yourself, this is most of it:
- Keep hard days apart, a hard run and a heavy leg session want a day between them
- If both fall on one day, run first and lift after, and keep the run the easy one
- Put heavy lower-body work as far as possible from your key run of the week
- Upper-body work barely interferes with running: that is your flexible day
- An easy run the day after a hard session is fine, and is how a week recovers
- When you add running volume, hold strength steady, and the other way round
What FitBoost does with that
Your week holds both. Each day is already assigned ( an upper-body session, an easy run, lower body, a longer run ) rather than you deciding on the morning and hoping it does not clash with yesterday.
If today does not suit you, you can ask for a run instead of the strength session, or the other way round, and it will swap when the week still works. You can also drag a session to a different day.
Training for a distance as well
The same sequencing is what makes strength work alongside 5K or half-marathon training rather than against it: strength stays, the heavy leg day moves away from the long run, and the hard running day is protected because that is the one the race actually depends on.
Questions
Can I run and lift on the same day?+
Yes. Run first and lift afterwards, and keep that run an easy one. Two hard efforts stacked in a day is the combination to avoid.
Should runners do leg day?+
Yes. Strength work is what makes a runner durable. Place it away from your hardest run of the week rather than dropping it.
How many days of strength should a runner do?+
Two is enough for most people running several times a week. FitBoost fits strength around the number of days you say you can train.
Does FitBoost plan running and strength together?+
Yes. Both sit in the same weekly plan, on separate days, and you can swap today’s session between the two.

How FitBoost builds these schedules
The placement rules on this page are the ones the app applies: hard sessions spaced apart, heavy lower body kept away from the key run, upper body used as the session that interferes least, and rest planned rather than left over. In the app they run against your own history, what you completed, what you skipped and what you reported as too hard, rather than against a template.
