When clinicians talk about exercise in schizophrenia, they usually mean walking, jogging, or some form of cardio. Resistance training — lifting weights, doing bodyweight exercises, or using resistance bands — gets less airtime. That is starting to change. The Firth group's meta-analyses and several recent trials have begun to document what gym-going people with schizophrenia have known for a long time: building strength does something distinctive that aerobic exercise alone does not.
Resistance training in schizophrenia improves body composition, insulin sensitivity, mood, and self-efficacy — and is often more sustainable than aerobic exercise for people who find cardio uncomfortable.
Why resistance training matters in schizophrenia specifically
Three biological realities make strength training especially relevant for this population:
- Antipsychotic-related weight gain. Many antipsychotics shift body composition toward more fat and less muscle. Resistance training is the most direct intervention for that imbalance.
- Insulin resistance. Antipsychotics can drive insulin resistance independent of weight. Skeletal muscle is the body's largest sink for blood glucose; building muscle improves insulin sensitivity even without weight loss.
- Self-efficacy. The visible, measurable nature of strength gains — adding 5 kg to a lift, completing one more rep — provides reward signals that compensate for blunted internal reward systems in negative symptoms.
The evidence base
The Firth and Vancampfort meta-analyses on physical activity in schizophrenia consistently include resistance training programmes among the active arms that produce benefit. A 2017 systematic review in Schizophrenia Research on physical fitness and schizophrenia found that combined aerobic-plus-resistance programmes outperformed aerobic-only programmes for body composition outcomes and matched them on psychiatric symptom outcomes. The combined approach is what most current guidelines recommend.
The WHO physical activity guidelines recommend that adults perform muscle-strengthening activities involving major muscle groups on two or more days per week. Most people with schizophrenia, like most adults globally, fall well below that target.
What resistance training can be
You do not need a gym, and you do not need barbells. Resistance training can take many forms:
- Bodyweight — push-ups, squats, lunges, planks, step-ups
- Resistance bands — inexpensive, portable, low intimidation
- Dumbbells or kettlebells — minimal home equipment
- Machines — gym-based, often easier to learn safely than free weights
- Free weights — barbells, more technique required, more potential for progressive overload
How much
The dose used in trials and recommended in general guidelines is approximately:
- 2 sessions per week covering all major muscle groups (legs, back, chest, shoulders, arms, core)
- 2–3 sets per exercise, 8–15 reps per set
- A weight that feels challenging by the last 2–3 reps
- Sustained for at least 12 weeks before judging effect
Practical strategies
If the gym feels intimidating
Start at home with bodyweight or bands. Many people find a few months of home training builds enough confidence and baseline strength to walk into a gym without feeling exposed. YMCA, community centre, and council gyms often have quieter hours and friendlier atmospheres than commercial chains.
If sedation is the problem
Train at the time of day when you feel most alert — for many on quetiapine or clozapine, that is mid-afternoon rather than morning. Short sessions (20–30 minutes) are easier to push through than long ones.
If motivation is the problem
Schedule sessions, write them down, and use a tracking sheet. The cognitive load of "deciding what to do today" is itself a barrier. Pre-printed beginner programmes solve this. Examples include simple full-body routines from sources like NHS Strength and Flex.
If you have never lifted before
A few sessions with a personal trainer experienced with mental illness is one of the best investments you can make. Most gyms offer one or two free introductory sessions. Tell the trainer about any medications that affect dizziness, balance, or heat tolerance.
Safety
You have known cardiovascular disease, are in the first weeks of clozapine (myocarditis risk), have significant orthostatic hypotension, or have had recent unexplained chest symptoms.
- Warm up. Five minutes of walking or easy movement before lifting.
- Stay hydrated. Antipsychotics can affect heat tolerance.
- Avoid breath-holding (the Valsalva manoeuvre) on heavy lifts, especially if you have orthostatic hypotension.
- Do not push through chest pain, severe dizziness, or palpitations.
- Sleep is part of recovery. Strength gains require sleep.
What to expect over time
The first 6 to 8 weeks usually bring noticeable strength gains driven by neural adaptation rather than visible muscle change. Body composition changes (more muscle, less fat at the same weight) typically appear by months 3–6. Improvements in mood and self-efficacy can show up within the first few weeks. Improvements in metabolic markers (HbA1c, lipids) generally require sustained training over 3–6 months and are amplified by combining strength training with attention to diet.
The relationship with antipsychotic weight gain
Resistance training will not, on its own, reverse all of the weight gain caused by olanzapine, clozapine, or quetiapine. But combined with modest aerobic activity, attention to ultra-processed food intake, and sometimes metformin, it shifts the trajectory meaningfully. Many people maintain or slowly improve their body composition on antipsychotics by training consistently, even without major dietary changes.
Why this matters beyond physical health
Negative symptoms strip out the experience of effort being rewarded. Resistance training puts that loop back together in a particularly direct way. Pick a number, lift a weight, write it down, lift more next time. The feedback is concrete. Many people with schizophrenia describe this as restoring something deeper than fitness — a sense that effort produces visible change.
