Catherine Tyldesley is back in her pre-pregnancy jeans just five months after giving birth to son Alfie.

The Coronation Street actress, who is already back to work on the cobbles, revealed that her doting fiance Tom Pitfield was key in helping her shed the weight she had gained.

Opening up about the achievement in her blog for Hello, the actress was quick to thank her husband-to-be but also admitted that she has since hired a new personal trainer to take the pressure off.

She said: "Big Thank you to my wonderful Tom for helping me, and to my new personal trainer @mattwarnerpt who is now helping me to achieve my fitness goals (I think Tom’s glad of the hand over to be honest… Nagging him about home improvements mid- workout didn’t go down to well!)."

Catherine was full of praise for her new personal trainer and assured fans that she would be sharing all of her fitness secrets in the coming weeks.

However, she also stressed to her followers the importance of losing weight healthily rather than resorting to extreme measures.

She added: "I’ve spoken previously about the importance of ‘rest days’. I used to train 6 days a week… Sometimes 7! Allowing my body very little time to recover and repair. At least two rest days are important. I still remain active on rest days e.g I walk with Alfie or go for a little swim, but I don’t lift weights.

"I also make the effort to take a Magnesium Salt bath after training – which helps you repair quicker. I recommend bathing in a pint of Magnesium Salts for at least 25 minuets. I also use a product new to the market- magnesium body butter! The idea being the same- aiding muscle recovery transdermally."
