To achieve Kate Beckinsale’s tight-fitting rubber catsuit, we checked with Jessica Alba’s personal trainer, Ramona Braganza. They used my 3-2-1 training method, using cardio, circuits and core work. She also filmed outside in the cold, to boost her metabolism.’

Kate’s workouts started with yoga-inspired stretches such as sun salutations and downward dogs, Braganza told Health & Fitness. These total body stretches get the blood flowing to all the major muscle groups.

The pair would then do some strength training for 45 to 60 minutes and Kate would finish the session with her own cardio.

When training, the actress asked Braganza to focus on her lower body. He said: ‘Kate works hard when she steps into the gym – we trained her full body, giving her legs and bum extra attention.’
