JuggernautAI vs RP Hypertrophy

JuggernautAI vs RP Hypertrophy, row by row

Same price, different goal: JuggernautAI for a bigger total, RP for more muscle. RIRLift is the free one in between, setting weights from your sets on iPhone and Apple Watch, without the meet planning or the feedback-driven volume.

How to choose between them

• Your goal decides it

  RP's help center says its app is for growing muscle and recommends JuggernautAI if strength is your main aim. Juggernaut says it specializes in powerlifting, and recommends its Powerbuilding program if muscle is the goal.

• What each asks before you lift

  Juggernaut checks your sleep, nutrition, strength and recovery before each session and adjusts the day's training. RP asks how pumped, sore and worn out you are, and moves your set counts.

• Meet day

  Enter a competition date and Juggernaut plans hypertrophy, strength and peaking phases around it, in blocks of 4 weeks or more, then recommends your opener, second and third attempts.

• The price

  Both are $34.99/month in the US. Juggernaut's two-week trial is only for sign-ups on its website; RP refunds website purchases within 30 days.

• Where RIRLift fits

  RIRLift logs reps in reserve on every set and sets the next weight from it, for heavy sets and volume work alike, free. It has no readiness check and no meet planning.

  

One lifter, two goals

A bigger bench and a bigger chest, no meet

Three years of lifting, four days a week, a 245 lb bench and no plans to compete.

App	What it does here	For this lifter
JuggernautAI	Powerbuilding or PowerCombo: training built around the squat, bench and deadlift, adjusted by RPE and a daily readiness check.	Fits if the bench number matters most.
RP Hypertrophy	A Meso Builder block with chest under Emphasize. Sets climb from your feedback; strength comes second.	Fits if the chest matters most.
RIRLift	Heavy bench sets and chest volume in one routine, every weight set from your reps in reserve, free. No meet planning.	Fits if you want both without $34.99 a month.

Without a meet, the question is which matters more, and how much you'll pay for an app to steer it.

Bench day in RIRLift

Same lifter. The Spoto press is planned at 5 reps with 2 left, in a 3–6 range.

Exercise	You logged	Next session	Why
Spoto Press	Set 1: 205 lb × 5, 3 left	Set 2: 210 lb × 5	8 reps to failure against a planned 7, so 205 × 37 ÷ 36 ≈ 211 lb, loaded as 210 lb.
Close-Grip Bench Press	175 lb, 8 / 8 / 8, 2 left	180 lb × 6	Every set at the top of 6–8: one 5 lb step, reps back to 6.

A heavy press and the volume after it, both moved by the same rule: the set you just did.

Make it fit you

• Turn RPE into RIR

  Juggernaut works in RPE. RPE 8 is 2 left, RPE 9 is 1. Set the targets once per exercise.

• Start from your numbers

  Tap Edit starting weights under the routine picker and enter your current working weights. They show as Yours, and the next weight is worked out from them. There's no max to test.

• Set the pace

  Push takes bigger jumps and waits longer before suggesting a step back. Steady takes smaller, surer steps.

• Plates on the wrist

  With Pro, the Watch shows plates per side, and you can enter your own plates and bar.

When a different app fits better

• You're peaking for a meet. JuggernautAI, which plans to your meet date and picks your attempts.
• You want volume set from pump and soreness. RP Hypertrophy.
• You log RPE and want to keep it. JuggernautAI. RIRLift logs reps in reserve.
• You train on Android. Either JuggernautAI or RP. RIRLift is iPhone and Apple Watch only.
