Is Spinning Good for Perimenopause Weight Gain?
Perimenopausal weight gain is driven by hormonal shifts, not just diet. Find out how spin classes can help and what else you need alongside them.
Why Weight Gain Happens During Perimenopause
Weight gain during perimenopause frustrates many women who feel they are eating and exercising the same as they always have, yet still watching the scales creep upward. The reality is that the hormonal changes of perimenopause fundamentally alter how the body stores and burns fat. Declining oestrogen shifts fat storage from the hips and thighs toward the abdomen, creating the characteristic midlife change in body shape that many women notice even when overall weight stays the same. Insulin sensitivity also decreases, meaning the body is less efficient at managing blood sugar and more prone to storing excess calories as fat. Muscle mass declines with age, and since muscle is metabolically active tissue, losing it slows the resting metabolic rate. Cortisol dysregulation common during this hormonal transition further promotes abdominal fat storage. Understanding these mechanisms makes it clear why targeted strategies are needed.
What Spin Classes Offer for Weight Management
Spin classes, also called indoor cycling classes, are a highly effective tool for managing perimenopausal weight gain for several reasons. A typical 45-minute spin class burns between 400 and 600 calories depending on body weight and effort level, making it one of the higher-calorie-burning cardio options available in a group fitness setting. The high-intensity interval format used in most spin classes, alternating between hard efforts and recovery periods, produces an afterburn effect known technically as excess post-exercise oxygen consumption. This means your body continues burning calories at an elevated rate for up to 24 hours after the session. Spinning also builds lower body muscle mass in the quads, hamstrings, and glutes, and greater muscle mass raises your resting metabolic rate over time, directly counteracting the metabolic slowdown of perimenopause.
The Role of Intensity in Hormonal Weight Management
The intensity of spin classes makes them effective for calorie burn, but it also means they need to be managed thoughtfully for women in perimenopause. Very high cortisol output from extremely intense or too-frequent spinning can worsen abdominal fat storage and increase appetite for high-calorie foods. Three to four spin sessions per week tends to sit in the sweet spot for most women, providing enough stimulus for fat loss and muscle maintenance without pushing the cortisol response into counterproductive territory. If you are new to spinning, start with two sessions per week alongside lower-intensity activity like walking, and build gradually. Mixing spin classes with strength training is particularly beneficial for perimenopausal weight management, as resistance work preserves and builds the muscle mass that keeps your metabolic rate healthy.
What You Eat Around Spin Classes Matters
Nutrition is the other side of the weight management equation, and perimenopause shifts the nutritional requirements that served you in your 30s. Protein needs increase during perimenopause because oestrogen normally supports muscle protein synthesis, and its decline means you need more dietary protein to maintain the same muscle mass. Aim for 1.2 to 1.6 grams of protein per kilogram of body weight per day, spread across meals. After a spin class, consuming 20 to 30 grams of protein within 30 to 60 minutes maximises the muscle-building signal from your workout. Reducing refined carbohydrates and ultra-processed foods helps manage the insulin sensitivity changes of perimenopause. Eating plenty of fibre-rich vegetables, legumes, and wholegrains supports gut health and blood sugar regulation, both of which are relevant to weight management during this transition.
Spin Class Practicalities for Perimenopausal Women
Hot flashes and temperature dysregulation make spin classes feel challenging for some perimenopausal women. Arriving early to position yourself near a fan or air conditioning unit helps significantly. Wearing moisture-wicking fabric and layering with a light jacket you can remove is sensible. Staying well hydrated before, during, and after class is important because sweating and perimenopausal hot flashes together can quickly deplete fluid levels. Many women find that the social energy of a group spin class provides motivation that solo exercise does not, which is a genuine advantage for consistency. If live spin classes feel too intense initially, cycling on a stationary bike at your own pace and building up to a class format works well as a stepping stone.
Managing Expectations Around Results
One of the most important mindset shifts around weight management in perimenopause is adjusting expectations away from purely scale-based metrics. Many women doing regular spin classes find that their body composition improves significantly, gaining muscle and losing fat, while the number on the scale moves more slowly than they hoped. This is a positive outcome. Reduced abdominal fat, improved muscle definition, better-fitting clothes, and higher energy levels are all meaningful markers of progress that the scale does not capture. Focusing on these alongside weekly measurements or progress photos gives a more accurate picture of what is actually happening. Perimenopause is also a time when the goal of arriving at a specific weight may be less relevant than the goal of maintaining metabolic health, cardiovascular fitness, and functional strength.
When to Combine Spinning with Other Interventions
For women whose weight gain is significant, rapid, or accompanied by other symptoms that are affecting quality of life, speaking with a GP or menopause specialist is worthwhile. HRT can help counteract some of the metabolic changes that drive perimenopausal weight gain, particularly abdominal fat accumulation, and it works best when combined with an active lifestyle. A registered dietitian who specialises in menopause can help you build an eating plan tailored to your changing hormonal environment rather than a generic calorie-restriction approach, which often backfires in this life stage. Spinning provides an excellent foundation. Combined with strength training, adequate protein, good sleep, and appropriate medical support where needed, it forms part of a genuinely effective strategy for managing your weight through perimenopause.
