Kayvan Seyri Personal Trainer’s Guide

Marylebone and Mayfair are two of London’s most dynamic and luxurious areas. Surrounded by boutique cafes, stunning apartments, and high-pressure careers, residents often face a big challenge: how to stay fit in a busy, compact, and expensive part of the city.
As a performance coach and personal trainer near Regent’s Park, I’ve worked with students, professionals, and local residents who want to get healthier but don’t know where to start. I’ve been approached by Marylebone residents, Mayfair executives, and university students looking for simple, no-equipment solutions that fit their lifestyle.
This guide brings together everything I’ve learned helping locals create smart, sustainable fitness routines — all designed for small spaces, tight schedules, and zero gym memberships.
Why Staying Fit in Marylebone & Mayfair Can Be Challenging
Through my work and daily interactions in the area, here’s what makes it harder for residents to stay consistent:
- Small flats → Limited space for workouts or equipment.
- Demanding careers → Finance, medicine, law, and other roles leave little free time.
- High gym costs → Boutique gyms can charge over £200-300/month.
- Congestion & pollution → Crowded roads discourage running and cycling.
- Lifestyle temptations → Surrounded by fine dining, wine bars, and takeaway options.
The result? Many people delay starting their fitness journey, feeling stuck and unmotivated.
The solution isn’t complicated. It’s about making small, consistent changes using local resources.
Real Insights from My Conversations with Residents
I regularly meet people at Regent’s Park, Marylebone High Street, and Santander bike stations who stop me to ask:
“Kayvan, how do I get started if I don’t want to join a gym?”
“How can I stay fit in my tiny flat?”
“Can I really get results training outdoors?”
I’ve helped dozens of people correct techniques, create easy plans, and build confidence. Students from Regent’s University, residents of Marylebone Village, and professionals on Harley Street all face the same issue — wanting a plan that fits their life.
Just recently, while training a client at Regent’s Park, someone passing by stopped to watch us. After a few minutes, she came over with a few questions about her running form. In less than 15 minutes, I helped her correct her biomechanics in a simple, easy-to-understand way.
Based on her preference and goals, I gave her a quick structured 5K running plan on the spot — nothing complicated, just efficient and realistic. She left motivated, confident, and with a clear next step.
That’s the beauty of training in Marylebone and around Regent’s Park — with the right guidance, you don’t need endless hours in the gym. Sometimes, one simple conversation can set you on the path to a sustainable, personalised fitness plan.
This guide reflects the exact advice I’ve shared — now available to everyone.
1. Use Santander Bikes + Regent’s Park Running Track

Santander bikes are one of the best fitness hacks for locals. There are stations at Marylebone High Street, Baker Street, Great Portland Street, and all around Regent’s Park.
Why I Recommend It
- Affordable: Only £1.65 for 30 mins
- Perfect warm-up tool
- Great way to explore the area
Quick 5K Fitness Plan
Step 1: Cycle Warm-Up → 5–10 mins on a Santander bike
Step 2: Run/Walk Loop → Use Regent’s Park Inner Circle (~4.3 km)
- Beginners: Alternate 2 min jog / 1 min walk for 20 mins
- Advanced: Continuous 5K run
 Step 3: Stretch & Mobility → 5 mins at the lake lawns
This structure helps beginners and busy professionals build stamina without needing a gym.
2. Use Regent’s Park Outdoor Running Track
Regent’s Park is a free outdoor gym — if you know where to look:
Quiet Lawns: Yoga, stretching, and bodyweight circuits
Outer Circle: Perfect for interval running and cycling
Primrose Hill: Ideal for hill sprints and leg conditioning
Chester Road Bars: Free calisthenics setup (pull-ups, dips, core work)

Many of my clients prefer open-air training over crowded gyms, and Regent’s Park provides endless options.
3. Simple 20-Minute Bodyweight Routine
For residents in Marylebone’s many small apartments, here’s an equipment-free workout anyone can do:
- 15 Air Squats against and bench available
- 12 Push-Ups (on knees if needed) or incline using the park benches
- 20 Walking Lunges
- 30-sec Plank Hold can be done on the grass or hold on the bences on your hands
- Repeat 3 Rounds
This takes just 20 minutes and helps strengthen your core, legs, and upper body — no weights required.
4. Healthy Eating Made Simple
Eating out is tempting in Mayfair and Marylebone, but smart choices make all the difference. My top spots for locals:
- Daylesford Organic: Healthy grab-and-go meals
- Waitrose: High-protein, balanced options
- Planet Organic: Supplements and snacks
At home, keep it simple:
- Stock eggs, oats, berries, Greek yogurt, frozen vegetables
- Prep your lunch ahead to avoid expensive takeaways
- Focus on whole, unprocessed foods most of the time
5. Build Habits That Last
The real challenge isn’t starting — it’s staying consistent. Here’s what works:
- Set small goals: Start with two park sessions a week
- Track progress: Use Strava, Garmin, or MyFitnessPal
- Train with a partner: Accountability doubles results
- Get expert guidance: Even one personalised session can boost confidence
Final Thoughts: Your Fitness, Your Lifestyle
Staying fit in Marylebone or Mayfair doesn’t require expensive gyms, hours of free time, or complicated routines. It’s about leveraging local resources and creating sustainable habits that fit your busy lifestyle.
