Running + strength training app.

One plan for your runs and your strength workouts.

FitBoost coordinates your running and strength training in one weekly plan, based on your goals, your schedule and the training you actually completed, instead of leaving you to reconcile two apps that have never heard of each other.

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.

Questions

Is there an app that combines running and strength training?+

Yes. FitBoost plans both into one weekly schedule rather than treating them as separate programmes, and spaces the hard sessions so they do not undercut each other.

I run 3 times a week and want to lift twice. Can an app organise both?+

Yes. Tell FitBoost how many runs and how many strength days you want and it assigns them across the week, long run at the weekend, hard run midweek, heavy legs away from both.

Is it free?+

Yes. No subscription, no in-app purchases, no ads and no account required.

Does it work for a half marathon?+

Yes. As race distance grows, the long run becomes the session the plan protects, and strength is placed to stay out of its way.
