If you’re taking hormone therapy, particularly an aromatase inhibitor, your risk of bone loss can increase over time because estrogen plays an important role in maintaining strong, healthy bones.
Exercise is one of the best ways to support bone health. However, not all exercises have the same effect on your bones.
Bones respond to load. Weight-bearing and resistance exercises place healthy stress on the skeleton, which signals your body to maintain or build bone.
In this video, Berfin, an oncology physical therapist, demonstrates 3 safe exercises:
1️⃣ Squats: Stand with your feet about hip-width apart. Keep your chest lifted as you bend your knees and push your hips back, as if sitting onto a chair. Press through your heels to return to standing. Start with body weight, then gradually add dumbbells as you get stronger. Begin with 2–3 sets of 6–8 reps.
2️⃣ Step-Ups: Place one foot on a sturdy step and drive through your heel to step up. As you come to standing, bring the opposite knee up toward 90°, like a marching position. Slowly lower back down with control. Complete 2–3 sets of 8–10 reps, either finishing all reps on one side before switching or alternating legs.
3️⃣ Farmer’s Carry: Hold a dumbbell or kettlebell in each hand with your shoulders relaxed and posture tall. Walk at a comfortable pace, keeping your core engaged and avoiding leaning to either side. Start with lighter weights and gradually increase the load as your strength improves.
A few important reminders:
✔️ Start with a weight that feels manageable while maintaining good form.
✔️ Progress gradually over time; your bones and muscles need time to adapt.
✔️ Focus on controlled movement and steady breathing rather than lifting heavier too quickly.
If you have osteoporosis or bone metastases, check with your healthcare team or an oncology rehab therapist before beginning a new exercise program.
For individualized guidance, we strongly recommend working with a therapist specialized in Breast Cancer Rehabilitation.
