Keeping her cool: Tamara Ecclestone barely breaks a sweat as the heiress smiles her way through her riverside workout

Everyone knows that the old adage advises us that 'no pain, no gain'.

So either Tamara Ecclestone is such a fitness fanatic that she barely breaks a sweat any more or she wasn't really trying and just hamming it up for the cameras.

The Formula One heiress was snapped being put through her paces by a personal trainer on the banks of the River Thames in London today.

But unlike most of us, who look hot, sweaty and very flushed in the face during a vigorous workout, Tamara didn't even have a hint of perspiration.

In fact, she even managed to smile her way through it, something which many of us would never be able to achieve as we'd be too busy grimacing in pain.

The reality TV star was with her trainer on Embankment and was snapped warming up before going for a run along the street.

She was then snapped on some pulleys as she stretched her arms and legs and was seen doing bench presses on a bench on the side of the road.

But it soon became all too much for her as she stopped to cool down with an ice cold bottle of water.

It's the first time we've seen Tamara working out or heading to the gym, unlike her sister Petra.

But apparently this is a new chapter for Tamara who took to her Twitter page to write: 'Turning over a new leaf, starting back at the gym and then Pilates.'

So her riverside workout was a good way of slowly starting her fitness regime.

Tamara, 27, recently spoke about her inherited wealth and how she is criticised for it, even though she is the woman who treats her pet
dogs to daily grooming sessions in Harrods and recently spent 18million
remodelling her 45million home.

She said recently: ‘At the end of the
day I’m just a normal 27-year-old girl. I enjoy shopping and going on
holiday. I’m proud of my dad and I’m very grateful that he’s afforded me
a nice life. But I am not going to spend the rest of my life
apologising for it.’
