Movement During Body Changes
Staying active during GLP-1 treatment is important for health, energy, and wellbeing. Yet finding appropriate exercise clothing while your body changes presents unique challenges. Athletic wear needs to fit properly for safety and comfort, but quality activewear is expensive. Buying new exercise clothes every few months feels wasteful, yet working out in ill-fitting clothing is uncomfortable and sometimes unsafe.
Whether you’re walking regularly, attending fitness classes, running, cycling, swimming, or simply want comfortable clothes for active daily life, you need practical solutions that work during transition without breaking the bank.
Understanding Activewear Needs by Activity
Walking and General Activity
Essential items: Comfortable shoes with proper support, weather-appropriate outerwear, comfortable trousers or leggings, basic tops.
Fit requirements: Moderate—clothes should be comfortable but don’t require the precise fit of high-intensity activities.
Budget approach: Mix of budget and quality items. Invest in excellent shoes; economize on clothing.
Minimum wardrobe: 1 pair quality walking shoes (£50-80), 2 pairs comfortable leggings or joggers (£15-30 each), 3 basic t-shirts (£5-10 each), 1 weather-appropriate jacket (£30-60), Total: £120-180.
Gym and Fitness Classes
Essential items: Supportive sports bra (if applicable), fitted leggings or shorts, moisture-wicking tops, proper trainers.
Fit requirements: Higher—ill-fitting clothes can be unsafe during equipment use or high-movement activities.
Budget approach: Invest in sports bra and shoes; budget options acceptable for other items.
Minimum wardrobe: 1-2 sports bras (£25-40 each), 2 pairs leggings (£20-35 each), 3 tops (£10-15 each), trainers (£50-100), Total: £150-250.
Running
Essential items: Quality running shoes, supportive sports bra, fitted bottoms, moisture-wicking tops.
Fit requirements: High—proper fit prevents chafing, provides support, and affects performance and safety.
Budget approach: Invest in shoes and sports bra absolutely; moderate spending on other items.
Minimum wardrobe: Running shoes (£80-150), 2 sports bras (£30-50 each), 2 pairs running tights/shorts (£20-40 each), 3 technical tops (£15-25 each), reflective jacket (£30-60), Total: £240-400.
Yoga and Pilates
Essential items: Fitted, stretchy leggings or shorts, comfortable sports bra, fitted tops that don’t ride up.
Fit requirements: Moderate to high—clothes need to move with you and not shift during inverted poses.
Budget approach: Quality leggings worth investing in; other items can be budget-friendly.
Minimum wardrobe: 2 pairs yoga leggings (£25-40 each), 2 sports bras (£20-35 each), 3 fitted tops (£10-20 each), Total: £120-190.
Swimming
Essential items: Well-fitting swimsuit, goggles, swim cap (for pool swimming).
Fit requirements: High—ill-fitting swimwear is uncomfortable and affects swimming ability.
Budget approach: Buy new swimwear in current size; this isn’t an area for compromise on fit.
Minimum wardrobe: 1-2 swimsuits (£25-50 each), goggles (£10-20), swim cap (£5-10), Total: £65-130.
Cycling
Essential items: Padded cycling shorts or bibs, moisture-wicking tops, cycling shoes (if using clipless pedals).
Fit requirements: High—cycling clothing needs to fit properly for comfort and performance.
Budget approach: Invest in quality padded shorts; other items can be budget-friendly cycling-specific or general athletic wear.
Minimum wardrobe: 1-2 padded shorts (£30-60 each), 2-3 cycling tops (£15-30 each), cycling jacket (£40-80), Total: £120-230 (plus shoes if needed).
The Core Exercise Wardrobe Formula
For most people engaging in moderate regular exercise, this formula provides everything needed:
Universal Exercise Wardrobe (Budget: £150-220)
Foundation:
- 1 pair quality athletic shoes (£60-100)
- 2 sports bras or supportive base layers (£30-50 total)
- 2-3 pairs leggings or joggers (£35-70 total)
- 3-4 basic athletic tops (£20-40 total)
- 1 outdoor layer (hoodie, jacket, or windbreaker) (£25-50)
This creates: A week’s worth of workout outfits, appropriate for most activities, washable and quick-drying.
Budget Shopping Strategies for Activewear
Budget High Street Options
Primark: Extremely affordable basics. Leggings from £5, sports bras from £4, tops from £3. Quality is acceptable for low-impact activities and temporary wear. Not suitable for high-intensity activities or long-term use.
Best for: Walking, light exercise, temporary workout wear. Complete basic workout wardrobe for £40-60.
Decathlon: Sports-specific retailer with excellent value. Their own-brand items (Domyos, Kalenji, Kimjaly) offer quality at low prices. Leggings from £10, sports bras from £8, running shoes from £25.
Best for: All activities. Complete workout wardrobe for £80-120 with decent quality.
Supermarket ranges: Asda, Tesco, and Sainsbury’s offer activewear lines with surprisingly decent basics. Leggings £8-12, sports bras £6-10, tops £5-8.
Best for: Walking, gym basics, general exercise. Complete workout wardrobe for £50-80.
H&M and Primark sport lines: Budget fashion retailers with dedicated athletic lines. Better quality than their cheapest basics. Leggings £12-18, sports bras £8-12, tops £6-10.
Best for: Gym, classes, general fitness. Complete workout wardrobe for £70-100.
Mid-Range Value Options
Decathlon premium lines: Higher-quality sports-specific items. Running tights £25, technical sports bras £15-20, technical tops £12-18.
Nike/Adidas outlet stores: Previous season premium brands at 30-50% off. Leggings £25-40, sports bras £15-25, tops £15-25.
TK Maxx: Premium athletic brands heavily discounted. Stock is inconsistent but worth checking. Find Nike, Adidas, Reebok, Under Armour, Puma at 50-70% off retail.
M&S activewear: Good quality at moderate prices. Known for excellent sports bras. Leggings £20-30, sports bras £16-25, tops £12-18.
Secondhand and Resale Options
Vinted and Depop: Huge selections of secondhand activewear. Many people buy workout clothes, barely wear them, then sell. Often find nearly-new premium brands at 30-40% of retail.
Best for: Leggings, tops, outerwear. Generally avoid secondhand sports bras (hygiene) and shoes (molded to previous owner’s feet).
Sports-specific resale platforms: Sites like The Revury specialize in pre-owned athletic wear.
Facebook Marketplace and local groups: Many people sell workout clothing collections when changing sizes. Bundle deals offer excellent value.
What to Buy New vs. Secondhand
Always buy new:
- Sports bras (hygiene and support degradation)
- Athletic shoes (molded to previous owner’s feet, compressed cushioning)
- Underwear and base layers
- Swimwear
Good secondhand options:
- Leggings and workout trousers
- Tops and t-shirts
- Outerwear (jackets, hoodies)
- Shorts
- Accessories (bags, water bottles)
Special Considerations
Sports Bra Fitting
Proper sports bra fit is crucial for comfort, support, and breast health:
Signs of correct fit: Band stays level around ribcage without riding up. Breasts are encapsulated or compressed without spillage. Straps stay in place without digging in. You can move comfortably without excessive bounce. No rubbing or chafing anywhere.
When to replace: Every 2-3 clothing sizes during weight loss. Every 6-12 months during stability (elastic degrades). Immediately if band rides up, straps slip, or support feels inadequate.
Budget approach: Buy 2 good sports bras in current size rather than 5 cheap ones. M&S, Decathlon, and Shock Absorber (at TK Maxx) offer excellent support at reasonable prices (£15-30).
Sizing changes: Weight loss typically affects band size before cup size. As you lose weight, you might go from 38D to 36D to 34D, for example.
Athletic Shoe Considerations
Proper athletic footwear is essential for injury prevention:
Activity-specific shoes: Running shoes for running, cross-trainers for gym, cycling shoes for serious cycling. Generic trainers acceptable for walking and light activity.
Foot size changes: Many people experience foot size changes with significant weight loss (typically 0.5-1 size down, occasionally more). Feet may narrow more than they shorten.
When to replace: Running shoes every 300-500 miles or 6-12 months. Cross-trainers every 12-18 months with regular use. When cushioning feels compressed or tread is worn.
Budget strategy: This is a priority investment area. Good shoes prevent injuries that cost far more than shoes in medical care and missed activity. Budget £60-100 for quality athletic shoes. Look for previous season models at 30-40% off (still excellent quality, just last year’s colors).
Where to save: Buy last season’s colors or models from outlets. Check sports retailers’ sales (January, July typically have significant discounts). Consider previous year’s models online at discount.
High-Impact Activity Considerations
For running, HIIT, or other high-impact activities, fit and support matter more:
Non-negotiable quality items: Properly fitted sports bra with high-impact support. Quality athletic shoes appropriate for activity. Leggings or shorts that stay in place during movement.
Where budget items work fine: Tops (as long as they’re comfortable). Outerwear. Accessories.
Safety consideration: Ill-fitting shoes or inadequate breast support during high-impact activity can cause injuries. Prioritize these items in your budget absolutely.
Weather-Specific Needs
Cold weather: Layering is key. Base layer (thermal top, £10-20), mid-layer (fleece or hoodie, £15-30), outer layer (windproof jacket, £25-60). Gloves, hat, buff (£10-20 total). Start with outer layer and add other pieces as needed.
Warm weather: Moisture-wicking fabrics essential. Lightweight, breathable tops (£8-15 each). Shorts or capri leggings (£10-20). Sun protection (hat, sunglasses).
Wet weather: Waterproof jacket (£30-80 for decent quality). Quick-dry fabrics. Visibility items if exercising in low light (reflective vest, £8-15).
Making Activewear Last Longer During Transition
Fit Extenders for Exercise Clothing
Drawstring waistbands: Workout trousers with drawstrings accommodate 1-2 size changes. When shopping, prioritize these styles.
Compression shorts under looser ones: As workout shorts become large, wear compression shorts underneath for support and coverage.
Layering for coverage: Longer tops over leggings that are becoming looser. Sports bra under tops that are gaping.
Rolling and adjusting: Roll waistbands on leggings that are becoming too large. Adjust straps on sports bras for extended wear.
Care and Maintenance
Wash after every wear: Sweat and bacteria degrade fabrics. Always wash workout clothes after use.
Cold water washing: Preserves elastic and prevents shrinking. Warm/hot water degrades activewear fabrics faster.
Air drying: Heat from dryers destroys elastic fibers. Air dry all activewear, especially sports bras and leggings.
No fabric softener: Coats moisture-wicking fabrics and reduces their functionality. Use regular detergent only.
Separate from rough fabrics: Wash activewear separately from jeans or items with velcro (causes pilling and damage).

Activity-Specific Budget Scenarios
Walking/Hiking Budget Approach
Priority spending: Excellent walking shoes or boots (£60-100), weather-appropriate jacket (£30-60), 2 pairs comfortable leggings or joggers (£20-40), 2-3 moisture-wicking tops (£15-30).
Total per size: £125-230
Where to save: Tops can be very basic. Decathlon, supermarkets, or charity shops all work fine.
Gym/Fitness Classes Budget Approach
Priority spending: 2 good sports bras (£30-50), cross-training shoes (£50-80), 2 pairs leggings (£20-40), 3 tops (£20-30).
Total per size: £120-200

Running Budget Approach
Priority spending: Quality running shoes (£80-150), 2 high-impact sports bras (£40-70), 2 pairs running tights (£30-60), 2-3 technical tops (£20-40), reflective gear (£15-30).
Total per size: £185-350
Where to economize: Previous season running shoes are excellent quality. Decathlon technical tops perform nearly as well as premium brands at fraction of price.
Swimming Budget Approach
Priority spending: 2 well-fitting swimsuits (£40-80), goggles (£15-30), swim cap (£5-10), post-swim cover-up (£15-25).
Total per size: £75-145
Where to save: Decathlon swimwear is excellent quality at low prices (£20-35 per suit). Speedo at TK Maxx offers premium brands discounted.
Motivation and Mindset
Celebrate with gear: When you hit exercise milestones, consider celebrating with one piece of nice workout gear. Completed a couch-to-5K program? New running shoes. Exercising consistently for three months? That premium sports bra or leggings you’ve wanted.
Function over fashion: During transition, focus on comfort and functionality. Express your style fully once you’ve stabilized.
Community resources: Many running clubs, walking groups, or fitness communities have clothing swaps or recommendations for budget gear. Don’t hesitate to ask.
Comparison is pointless: Someone else’s premium athletic wardrobe doesn’t make them healthier than you in your budget gear. The movement matters, not the label.
Temporary is okay: These clothes are temporary. Buying what you need to stay active now is smart, not wasteful.
