Description of intervention(s) / exposure
BEHAVIORAL - Physical Exercise
BEHAVIORAL - Stress management training A
BEHAVIORAL - Stress management training B

Active comparator: Physical exercise + stress management activity A - Eight week program of concurrent exercise and stress management training.

Active comparator: Physical exercise + stress management activity B - Eight week program of concurrent exercise and stress management training.

No intervention: Lifestyle as usual - Eight weeks period with no alteration of usual lifestyle.

Participants randomized to this arm are eligible for re-randomisation to one of the active conditions at the conclusion of week eight.


BEHAVIORAL: Physical Exercise
Physical exercise: Amount of time exercising gradually titrated from 90-minutes in week one to 180-minutes in week eight. Intensity titrated concurrently from 40 - 60% VO2 max in week one to 40 - 90% VO2 max in week eight. Eight week gym membership provided to all participants to facilitate engagement in exercise.

BEHAVIORAL: Stress management training A
Stress management training A: Daily stress management training for eight weeks with training activity delivered via app. Session lengths titrated from 10-minutes per day in the first week to 20-minutes per day in week eight.

BEHAVIORAL: Stress management training B
Stress management training B: Daily stress management training for eight weeks with training activity delivered via app. Session lengths titrated from 10-minutes per day in the first week to 20-minutes per day in week eight.

Summary
Brief summary
Following the realisation that many aspects of the way we live our life, such as our diet, activity levels, and amount of screen time, can have a potent impact on mental health and brain functioning 'lifestyle' based interventions have become topical in medical research. In particular, much scientific attention has been devoted to the impact of physical exercise and various stress reduction techniques on mood disorders. We aim to extend this work and investigate their impact on compulsivity.

We will do this by conducting a pilot proof-of-principal intervention study. The study will compare the impact of eight-weeks of:

1. regular physical exercise + stress management activity A,
2. regular physical exercise + stress management activity B,
3. lifestyle as usual.

The participant cohort will be adults who endorse mild-moderate behavioural compulsivity on one of the following domains:

* drinking alcohol
* gambling
* eating
* washing or cleaning
* checking
* ordering or arranging objects
