Caliber vs Fitbod

Caliber vs Fitbod, row by row

Fitbod for an app that decides the session; Caliber for a free start and a human coach when you want one. RIRLift sits between them: your routine, its weights, free.

What actually separates Caliber and Fitbod

• Who decides today's workout

  Fitbod builds a new session each time from your goal, equipment, time and recovery. Caliber gives you a plan to follow: your own, one of 120+ Plus plans, or one your coach writes.

• What you pay before you start

  Caliber's app is free and stays free. Fitbod asks you to pick a plan up front, then charges $15.99 a month or $95.99 a year after 7 days.

• Whether a person is involved

  Fitbod is all algorithm, with no calls or check-ins. Caliber's Premium Coaching is a real trainer who reviews form videos and your week, from about $200 a month.

• How weights move

  Fitbod suggests weights from your logged data. Caliber fills in last session's numbers and leaves the jump to you or your coach.

  

• The routine-plus-weights middle

  RIRLift keeps your routine the same each week and sets every weight from the set you just did, free. How it decides.

Caliber or Fitbod, in two real cases

Fitbod trial ends Friday, Caliber is already installed

Second year of lifting, legs twice a week at a big gym. Liked that Fitbod picked weights, doesn't want a new workout every day, and won't pay $200 for coaching.

App	What it does here	For this lifter
Fitbod	Keeps building fresh sessions and suggesting weights, for $15.99 a month or $95.99 a year.	Good if the variety is the point. It isn't, here.
Caliber free	Logs the same leg days for free and fills in last time's numbers.	Keeps the routine, loses the weight picking.
Caliber Premium	A coach writes the leg days and adjusts them weekly, from about $200 a month.	Over budget.
RIRLift	Keeps the two leg days as routines and sets each weight from load, reps and reps left. Free.	The routine and the weights, at $0.

The choice was never only Caliber or Fitbod. It was who picks the weight, and what that costs.

Leg day, the first set goes badly

The same lifter in RIRLift. Hack squat planned for 8 reps with 2 left in a 6–10 range; leg extensions in a 10–15 range.

Exercise	You logged	Next session	Why
Hack Squat	Set 1: 270 lb × 5, 1 left	Set 2: 255 lb × 8	Five is below the 6–10 range, so it comes down, by at most 7% a set: 6 reps to failure against a planned 10 gives 270 × 35 ÷ 39 ≈ 242 lb, held to 270 × 0.93 ≈ 251 lb, loaded as 255 lb.
Leg Extension	110 lb, 12 / 11 / 10 reps, 2 left (target 10)	110 lb × 11	The weakest set hit its target of 10. Same weight, aim for 11.

A bad first set changed one number, set 2, and left next week's progress alone.

Make it fit you

• Rebuild your sessions as routines

  Fitbod's sessions change each time, so pick a plan from the program library or ask Coach for one built around your gym and days.

• Tell it your equipment

  Choose what your gym has once. Plans and swaps stay inside it, and every weight rounds to a step you can actually load.

• Start each lift from a measured set

  RIRLift can't read Caliber or Fitbod history. A light starting weight and one max-reps set give each lift its first real number.

• Choose a pace

  Steady takes smaller steps, Standard is double progression, Push takes bigger jumps. Pick Ask first to confirm next session's weights yourself.

• You want a human coach and form checks. Caliber Premium Coaching. Neither Fitbod nor RIRLift has one.
