Exercise (aerobic + resistance)
Specifically for Breast Cancer
0 up • 0 down
Why it works for Breast Cancer:
Symptom control & function. Large guideline panels reviewing dozens of randomized trials conclude that exercise reduces cancer-related fatigue and improves cardiorespiratory fitness, strength, physical function, anxiety/depression, and quality of life during and after treatment. ASCO explicitly recommends both aerobic and resistance exercise during active treatment with curative intent. Guideline Central
Safety (including lymphedema). Progressive resistance training is safe for women with or at risk of breast-cancer–related lymphedema and does not worsen swelling (PAL trials and follow-ups). New England Journal of Medicine
Mechanisms (how it helps your biology). Contemporary reviews detail plausible anti-cancer pathways: improved insulin/IGF signaling, lower systemic inflammation and oxidative stress, favorable sex-hormone modulation, myokine release, and epigenetic effects—mechanisms that overlap with lower recurrence/mortality in observational cohorts. MDPI
Survivorship & lifestyle guidance. The American Cancer Society Survivorship Guideline (2022) advises all survivors to be physically active to enhance wellness and potentially improve outcomes. ACS Publications
How to use for Breast Cancer:
These prescriptions are drawn from the ACSM international exercise-oncology roundtable and major society guidelines and are suitable during chemotherapy/radiation (with day-to-day adjustments) and after treatment. Start where you are and progress gradually.
Weekly targets
- Aerobic: Aim for 150 minutes/week of moderate activity (e.g., brisk walking, cycling) or 75 minutes/week vigorous, or an equivalent mix. Break into 20–40 minute sessions on 3–5 days/week. aim.clinic
- Resistance (strength): 2–3 non-consecutive days/week; target 8–10 exercises covering major muscle groups; 1–3 sets of 8–12 reps each; start light, progress slowly (e.g., +2–10% load once you can comfortably do >12 reps). aim.clinic
- Flexibility/mobility: Gentle stretching most days, especially for shoulder/chest wall mobility post-surgery or radiation. aim.clinic
Symptom-targeted “doses”
ACSM summarizes effective “doses” for common problems:
- Fatigue: ≥3 sessions/week, ≥12 weeks, moderate-intensity aerobic ± light-to-moderate resistance; benefits do not require high intensity. aim.clinic
- Anxiety/depression/HRQoL: Mixed aerobic + resistance across 8–12+ weeks is beneficial. aim.clinic
Practical starter plan (example)
- Mon – 25–30 min brisk walk + 2 sets each: sit-to-stand, wall push-ups, resistance-band row, mini-squats (8–12 reps).
- Wed – 25–30 min cycling or walk-intervals.
- Fri – 25–30 min walk + repeat strength (add shoulder mobility and gentle pectoral stretches).
- Adjust intensity down on “tough treatment” days; the goal is consistency, not perfection. Guideline Central
Supervision & tailoring
If available, working with an accredited exercise physiologist/physical therapist experienced in oncology improves individualization and safety (widely recommended in Australia by ESSA/COSA; similar messages in NCCN Survivorship). COSA

Specific Warnings for Breast Cancer:
Get medical input first if you have any of the following:
- Bone metastases or fragile bones: Avoid high-impact and loaded spinal flexion/twisting; emphasize posture, balance, lower-risk strengthening; individualize by lesion site/stability. (See ASCO expert recommendation on exercising with bone mets; practical tables in ACSM Roundtable.) ASCO Publications
- Ports/lines, recent surgery, axillary web syndrome (cording), or radiation skin reactions: Progress upper-body loading gradually; keep skin clean/dry; stop if new swelling, redness, or wound issues occur. (ACSM programming notes.) aim.clinic
- Cardiotoxic therapies (e.g., anthracyclines, trastuzumab) or cardiac history: Favor moderate intensity; consider baseline cardiac assessment and symptom-guided progression. (NCCN/ACSM safety sections.) aim.clinic
- Marked anemia, neutropenia, or thrombocytopenia: On low blood counts, modify or pause intensity/impact to reduce dizziness, infection, or bleeding risk; institutional handouts outline count-based caution ranges. Discuss with your oncology team and follow local thresholds. healthonline.washington.edu
- Peripheral neuropathy/balance problems: Prioritize stable surfaces, machines over free weights, handrails, and balance work; avoid trip hazards. (ACSM safety.) aim.clinic
- Uncontrolled pain, fever, unexplained shortness of breath, chest pain, or new/worsening swelling of an arm: Stop and seek medical review before resuming. (ACSM/NCCN safety triage.) aim.clinic
General Information (All Ailments)
What It Is
Exercise refers to structured, purposeful physical activity performed to improve or maintain physical fitness and overall health. It generally encompasses two main types:
- Aerobic Exercise (Cardio): Continuous, rhythmic activities that use large muscle groups and elevate heart rate and breathing for an extended period. Examples include walking, running, swimming, or cycling. Aerobic exercise primarily targets the cardiovascular and respiratory systems.
- Resistance Exercise (Strength Training): Activities designed to improve muscle strength, endurance, and power by working against a force or resistance—such as weights, resistance bands, or body weight. Examples include weightlifting, push-ups, or squats.
When combined, aerobic and resistance exercise form a comprehensive fitness approach that enhances cardiovascular health, muscular strength, endurance, flexibility, and body composition.
How It Works
Aerobic exercise works by increasing the efficiency of the heart, lungs, and circulatory system. During sustained movement, the body requires more oxygen to produce energy, leading to improved oxygen uptake (VO₂ max), stronger heart muscles, and enhanced capillary density in tissues. This, in turn, reduces the workload on the heart and improves endurance over time.
Resistance training works through a process known as muscle adaptation. When muscles are exposed to resistance, small microscopic tears occur in the muscle fibers. The body repairs these fibers by fusing them, resulting in stronger and larger muscles (hypertrophy). Additionally, resistance training enhances neuromuscular coordination, increases bone density, and boosts resting metabolism, as muscle tissue consumes more energy even at rest.
When both exercise types are integrated, the result is a synergistic effect—improving both cardiovascular efficiency and muscular strength, supporting overall physical performance, and optimizing body composition (more lean muscle, less fat).
Why It’s Important
Regular aerobic and resistance exercise provide a wide range of health benefits:
- Cardiovascular Health: Aerobic exercise reduces the risk of heart disease, lowers blood pressure, improves cholesterol balance, and enhances circulation.
- Metabolic Health: Combined training improves insulin sensitivity, helps regulate blood glucose, and supports healthy weight management.
- Musculoskeletal Strength: Resistance training prevents muscle loss with age (sarcopenia), enhances bone density (reducing osteoporosis risk), and improves joint stability.
- Mental Well-being: Both exercise types release endorphins and neurotransmitters (like serotonin and dopamine) that reduce stress, anxiety, and depression, while improving mood and sleep.
- Functional Fitness: The combination enhances balance, coordination, and mobility—key factors in maintaining independence, especially in older adults.
- Longevity: Regular exercise is associated with reduced risk of chronic diseases such as cardiovascular disease, type 2 diabetes, obesity, and certain cancers, contributing to longer, healthier lives.
Considerations
While exercise offers extensive benefits, several considerations are important for safety and effectiveness:
- Individualization: Exercise programs should be tailored to personal fitness levels, goals, and health conditions. Beginners should start gradually to avoid injury.
- Medical Clearance: Individuals with chronic diseases (e.g., heart conditions, diabetes, arthritis) or those over 40 who have been inactive should consult a healthcare provider before starting an exercise regimen.
- Balance and Progression: It’s important to balance aerobic and resistance sessions to prevent overtraining or burnout. Gradual increases in intensity, duration, and resistance yield better long-term results.
- Technique and Recovery: Proper form in resistance exercises prevents injury, while rest days are essential for muscle repair and adaptation.
- Nutrition and Hydration: Adequate protein supports muscle recovery, and hydration maintains performance and thermoregulation.
- Consistency: Sustainable results come from regular participation—ideally, most days of the week for aerobic activity and 2–3 times weekly for resistance training.
