Summary

What Is This Study About? To find out whether carrying heavy shopping bags twice a week can help adults not currently meeting physical activity strength guidelines improve muscle mass, strength, power, and endurance.

What Can Be learnt?

* Can carrying shopping bags help improve muscle mass, strength, power, and endurance?
* Should carrying shopping bags be included within physical activity recommendations?

Two groups will be compared:

* One group will carry shopping bags twice a week within a controlled lab environment
* The other group won't change anything in their routine.

What Will Participants Do?

* Self-select a weight for shopping bags that is heavy but can be carried for 15 minutes to use for all sessions
* Walk with shopping bags for 15 minutes at a normal walking speed for carrying shopping home from the supermarket.
* After each minute, the time stops and participants place bags on the floor. The time restarts for the next minute when the participant chooses to pick up the bags again.
