From medication to motivation

Joan’s transformation began in January 2017 when she was 70. In her Instagram Highlights, she revealed that at 198.6 pounds (90 kg), she was struggling with high blood pressure, acid reflux, vertigo, and painful arthritis. Faced with increasing dosages of medication, Joan decided to make a change, leaning on her daughter — a fitness professional — to help her navigate the world of weight training and macronutrients. Over the first three years, Joan lost 65 pounds (29 kg) through steady, sustainable progress.

Joan's fitness routine

Joan doesn't just stay active; she trains with intent. Her current regimen is more rigorous than many people half her age, focusing on a mix of heavy resistance and consistent cardiovascular work.

⦿ Proper warm-up: Joan begins every session with a dedicated warm-up to prepare her joints and muscles, especially important given her history with arthritis.

⦿ Strength training, five times per week: Her workouts include heavy compound movements like bench presses, kettlebell squats, lat pulldowns, and machine chest presses. She notes that in the beginning, she relied more on machines to manage pain before transitioning to dumbbells.

⦿ Cardio integration, 3–7 times per week: Depending on her current goals, Joan performs between 15 and 45 minutes of cardio per session to maintain heart health and stamina.

⦿ Post-workout stretch, 15 minutes: Every session ends with a full 15-minute stretching routine to aid recovery and maintain flexibility.

Joan's diet and lifestyle

Joan’s success isn't just about what she does in the gym; it's about how she fuels her body and mind. She is a staunch advocate for 'planning macros' (protein, carbohydrates, and fats) rather than just counting calories.

⦿ Nutrition: She prioritises high protein (targeting approximately 150 gram daily) and drinks 3 litres of water per day. She avoids performance-enhancing drugs, steroids, or HRT, attributing her results to natural consistency.

⦿ Mental sharpness: To combat mental ageing, Joan uses apps for meditation, cognitive training, and Duolingo to practice Spanish.

⦿ Joint support: She is transparent about her limitations, using knee braces or sleeves for leg days and previously using a corset to support her posture and back during her heavier weight-loss phase.

Joan MacDonald’s lifestyle isn't just impressive, it is a textbook example of the World Health Organisation (WHO) guidelines for physical activity for adults aged 65 and older.

Joan does three to seven sessions of 15–45 minutes, exceeding the recommended 150–300 minutes of moderate activity. WHO suggests two or more days/week; Joan trains with weights five days/week. WHO highlights functional balance and strength three or more days/week to prevent falls; Joan’s heavy lifting and stretching satisfy this. Joan replaces sitting time with movement, which WHO notes provides significant health benefits for older adults.
