People with schizophrenia display a broad range of cognitive impairments that have been identified as major determinants of poor functioning and disability. Also, people with schizophrenia are at increased risk for suicide, with approximately 40-50% of individuals attempting to take their own lives during their lifetime. The goal of the proposed study is to examine the impact of remote exercise training on cognition, suicide risk, daily functioning, and biomarkers of cognitive change and suicidality in people with schizophrenia.


Inclusion Criteria:

- A DSM-V diagnosis of schizophrenia, schizoaffective, or schizophreniform disorder.

- Age 18-55 years.

- Taking antipsychotic medication for at least 8 weeks and on current doses for 4 weeks, and/or injectable depot antipsychotics with no change in the last 3 months.

- Capacity to understand all the potential risks and benefits of the study.

- Medically cleared by a physician to take part in VO2max tests and aerobic exercise training or stretching-and-toning exercise training.

Exclusion Criteria:

- History of seizures/head trauma with loss of consciousness (>10 minutes) resulting in cognitive sequelae.
