Only Good Reps Count: Strength Test with a Form Judge

A muscular endurance test with five exercises (box squat, push-up, glute bridge, inverted row under a bench and side plank) where a partner acts as judge and only counts reps that meet the form criteria. Total reps and valid reps are recorded together so students see that technique is part of the result and of injury prevention.

How to play

1. Present the validity criteria for each exercise, for example for the squat: touch the box, knees in line with the feet and a firm trunk; judges practice with a demo (5 min).
2. Set up five stations with groups of six: two perform, two judge and two keep time (2 min).
3. Each performer works for 40 seconds; the judge counts out loud only the valid reps and also records the total, across all five stations. Roles rotate within the group at each station so everyone performs at every station (15 min).
4. Each student calculates their percentage of valid reps per exercise and marks the one where fatigue costs them the most form (3 min).

Rules

• If form breaks down for three reps in a row, the judge stops the set even if time remains.
• Boxes or benches are placed against the wall or held so they do not slide.
• In the side plank, switch sides halfway through.
• Each performer chooses the exercise version (with or without support) and records it on the sheet.

Variations

Adaptations

• Limited leg mobility: replaces squats and bridges with resistance band presses and seated medicine ball throws.
• Wrist injury: does push-ups and plank on the forearms.
• Hearing impairment: the judge raises fingers for a valid rep and shows an open palm for an invalid one.

Learning goals

• Assess muscular endurance using proper form criteria.
• Recognize how fatigue breaks down form and raises injury risk.
• Act as a judge with objective criteria and communicate them clearly.

Equipment for a class of 25

• exercise mats: 15
• boxes or benches: 5
• stopwatch: 5
• worksheets: 30

Teacher tip

At first, judges tend to count everything: stop the first station and correct the criterion out loud with an example. The percentage of valid reps is great data for planning the technique work of the unit.
