Experimental: Intervention group - telephone and print exercise intervention
The intervention group (IG) received a total of three intervention packages, one every second month, during the intervention period.
The first intervention package was distributed at intervention start.
The intervention package consisted of a tailored exercise program, national recommendations for physical activity, prompts and reminders.
Additionally the IG received fortnightly supportive motivational contact every two weeks, alternately by telephone og email
