ISO TRAINERIsometric strength testing and training system
Strength, measured.
A 500 kg force sensor and the coaching platform built around it. Measure maximal strength to the kilogram, then train, rehabilitate and benchmark off the number.
01Why isometric
One number every coach, clinician and athlete agrees on.
An isometric test takes fifteen seconds, needs no technique coaching and loads the joint at one angle. That makes it the fastest repeatable strength measurement available, and the safest one to run on a patient two weeks after surgery.
Measure
A max in under three minutes
Three maximal pulls, 120 seconds rest, and the best attempt becomes the reference max. The app shows the variation between attempts and suggests a fourth when the athlete is still climbing.
Train
Every target relative to the person
An 80 % hold means 80 % of that client's max, on that exercise, on that side. The screen coaches the zone live. Nothing is prescribed in absolute kilograms unless the coach wants it that way.
Prove
Symmetry, rate of force, trend
Left against right, this month against last, rate of force development at 100, 200 and 300 ms. The report is a PDF the referring doctor can read without a phone call.
02The system
Force Block and Iso Trainer. Sold and supported as one.
The Force Block is a 500 kg load cell that streams force over Bluetooth at 250 samples per second. The Iso Trainer app turns that stream into a max test, a target zone, a client record and a report. Neither is sold without the other, because neither is complete without the other.
- Verified zero, every effort. The app confirms an unloaded baseline before each test or exercise. It never trusts a zero from an earlier connection.
- Signal quality on every attempt. Sampling rate and continuity are graded per attempt. Explosive metrics appear only when the signal supports them.
- Anchors anywhere. Rack, floor plate, door anchor or the optional wall rig with numbered pin positions.
Live training · effort phase · ghost = last attempt · gold rule = PR
03The app
The screen coaches. The coach watches the athlete.
Green in the zone, amber below, red above, gold when a record falls. The athlete reads one number from across the room. The coach gets peak, hold time and rate of force development without touching the phone.
Modes
Max test, target hold, beat record, repeated max, endurance, ladder, progressive curve, explosive, custom.
Built in
26 exercises, 14 protocols, return-to-sport battery, tendon and blood-pressure programs, leaderboards, TV mode.
04How it works
Four steps from unboxing to a documented baseline.
Anchor
Strap or handle to the Force Block. Force Block to a rack, floor anchor or the wall rig.
Zero
The app verifies an unloaded zero from independent sample windows before every effort.
Test
Three maximal five-second pulls with a fixed instruction. The best becomes the reference max.
Train
Pick a protocol. The screen coaches the zone and every attempt saves to the client's record.
05Who it is for
Same system. Different first sentence.
