Switch to a lighter plan

Sessions keep slipping, which reads as a scheduling problem, not a motivation one. Trimming the plan to match what the week allows tends to fix it.

What you’d see in the app
01
Strength

Next session is already set

Fortiv reads your last session and sets weights, reps and rest for the next. You show up and lift.

Zone 2

Cardio that builds a base

Easy, sustainable minutes that build your engine. Fortiv tells you when you’re drifting off target.

Fortiv zone 2 cardio over six months — weekly minutes climbing from near zero in May to around 350 by October, with a 129–141 bpm zone 2 range set from a 58 bpm resting heart rate

Trends

The trend, not the daily noise

Bodyweight bounces day to day. Strength builds over months. Fortiv shows the line that matters.

Built by someone who lived it.

Questions,
answered.

How is this different from the fitness apps I’ve already quit?

Those apps assume you’ll follow the plan. Fortiv assumes some weeks you won’t. It watches strength, cardio and consistency together, and when the plan stops fitting your life it names one thing to change, instead of letting you quietly fall off.

Will it nag me or change my plan on its own?

No. Fortiv surfaces one recommended change when it sees drift. It never applies it for you and it never edits your plan behind your back. You’re an adult. You make the call.

Who is Fortiv for?

Adults 35–55 who want real strength and longevity without reorganizing their life around the gym.

I only have 2–3 days a week.

That’s the design point. Plans are built around the time you actually have, not an idealized schedule.

Do I need a full gym?

No. Fortiv adapts to what you’ve got, a full rack or a single pair of dumbbells.

Is it iOS only?

Yes. Fortiv launches on iPhone. Android is on the roadmap.
