About Me

I am Mary Hastings a qualified personal trainer, hatha yoga teacher and breath coach

What Can I Do For You?

My clients usually enjoy training at home, a local park or at the local personal training studio I am affilliated with. I have enough small equipment to ensure our hour together will be packed full of varied and  goal specific exercises geared towards your own abilities and likes.

At the moment I am successfully working with clients online. Clients find this really convenient as I am able to split a one hour session into two, which is more manageable for busy schedules. 

With the extra qualification of Hatha Yoga Teacher you willl have the choice to add this into your session, no experience or flexibility required from you! Maybe you've always fancied trying yoga but didn't want to commit to a class.

As your fitness coach, nutrition is key to weight loss and a healthy life so we will discuss your current eating habits.

Please see the full list of my qualifications below and you will see I am more than a Personal Trainer. I can offer you a range of expertize & life experience. The sessions will be designed specifically for you, taking into account your own set of circumstances & requirements.

Please also get in touch to hear about the following online classes I run on Zoom:

Monday Yin 5.30-6.30pm

Working with Mary as my PT has absolutely changed my life! She is incredibly supportive, kind, caring and pushes me to be better than I think I am. I have learned so much about what my body is capable of and love what I have achieved through training with Mary. I cannot recommend her highly enough; everyone should have Mary in their lives! Sarah Anderson. London.


“Mary and I met in London when I was living there, as I needed to exercise and especially stretch. Mary was a very good instructor who went at my pace, though not too slowly, after each session I felt invigorated, healthier and not to mention generally looked much better!. - Luca, South Kensington



"I trained with Mary for almost 2 years and always looked forward to our weekly session.  Mary constantly included new exercises making the sessions very enjoyable, never boring and great fun as well as being challenging and effective.” Nadine, London Bridge

"I have been seeing Mary at home for some exercise sessions. I really enjoy the time I have going through my paces on my sitting room floor.  The sessions are relaxed and tailored to suit the individual which is so important regardless of age or state of body or indeed mind...   I always feel invigorated after the session and ready to face the world" - Gail, London

“To my amazement I am enjoying our sessions, which for someone who avoids all things physical is impressive.  Thanks. Priti.”

“Morning, I've now lost 7.2lbs 😃 my goal was to lose 7lbs before holiday 😃😃 Feel like I'm building good muscle tone. Thank you xx” Claire

“Thanks Mary, you are really helping me stay motivated and positive” - Laura


"I wanted to lose some weight and tone up and started working with Mary in August 2011.  Ever session is different, always doing high fat burning exercises which are fun as well as effective.  I have lost over a stone and have dropped nearly 2 dress sizes and am now a size 12/14 in 6 months and have improved my general fitness and have some muscle definition.  The exercises we do are simple and I can do most of them by myself if I want to.  The sessions are a mixture of sparring, free weights, using the vipers, and occasionally using the cardio equipment.  Mary will tailor the sessions around what I enjoy and if there are certain exercises I don’t enjoy, we don’t do them again.

I have always felt that Mary listens to what I need and how I like to train.  From the very beginning, I felt comfortable and able to be completely honest with her so if I have had a bad week and eaten or drunk more than I should have I am not worried to tell her as she does not judge me for it.  Instead, she offers advice on how to reduce my calorie intake whilst still being able to enjoy all types of food.  She is very supportive during the week as well as at our sessions, I am able to text or email her at any time and she will always respond quickly so I fell that I have the support whenever I need it.  I would recommend Mary to anyone who is looking for a personal trainer" Emma, London
