Seconds Bank: A Class Record of Combined Strength Holds

In pairs, each student picks a strength hold and a level, and their partner times how long they keep it with good form. All the seconds go into a class bank that's plotted on a graph and the class tries to beat it in later lessons.

How to play

1. Core activation and explanation of three holds: front plank, side plank and wall sit, each with two levels (5 min).
2. Round 1 in pairs: one student holds while the other times and calls out if form breaks; switch roles (5 min).
3. Groups add up their seconds, and the class total goes on the poster-board graph (3 min).
4. Round 2 with a different hold or level chosen by each student (5 min).
5. Read the graph: today's total vs. last lesson, and a shared goal for next time (2 min).

Rules

• The clock stops when form breaks, not when you run out of strength.
• Only the class total goes on the graph, never individual times.
• Everyone picks a level they can do well.
• If your back or wrists hurt, stop and switch holds.

Variations

Adaptations

• Limited mobility: seated isometric holds for arms or core, such as pressing hands together.
• Students with visual impairments: the partner corrects form with verbal cues and a light touch if they're okay with it.
• Students with an injury: choose a hold that doesn't load the injured area, or act as timer and scorekeeper.

Learning goals

• Improve core and leg muscular endurance.
• Keep good form under effort.
• Work together toward a group goal using data.

Equipment for a class of 25

Teacher tip

A poster-board graph hanging in the gym motivates far more than a sheet in a folder; if you prefer digital, use a shared spreadsheet. Common mistake: holding with sagging hips to bank more seconds, so the timer must stop the clock.
