ELIZABETH  K – CASE STUDY | LOST 2 STONE & CLIMBED 3 YORKSHIRE PEAKS

Elizabeth K – Starting Point: 269.8 lbs.

At the start of her journey, she weighed 269.8 lbs. Over the course of her transformation, she lost 28.4 lbs (12.8kg), bringing her weight down to 241.4 lbs while dramatically improving her fitness, confidence, and lifestyle habits.

A year before starting personal training in Leeds with CSS Fitness, she had previously attempted the Yorkshire 3 Peaks but only managed 1 and a half peaks before having to stop. That experience left her doubting her physical capabilities, but also motivated her to come back stronger.

Goals & Expectations

There were two clear objectives from the beginning:

  1. lose weight
  2. Build enough fitness & resilience to complete the Yorkshire 3 Peaks challenge in one attempt

Alongside the physical goals, she also wanted to:

  • Make healthier lifestyle choices
  • Feel more confident and consistent heading into the summer months
  • Overcome self-doubt from her previous experience with the Yorkshire Peaks

Nutrition & Accountability

She learned how to manage her weekly calorie intake while still enjoying social occasions.

Regular weigh-ins and accountability check-ins ensured she stayed on track and continued progressing towards her goals.

The Training Approach We Used

For Elizabeth K, we used a full body approach

Training frequency: 3x Strength & resistance sessions, and 2 cardio dedicated sessions

The goal was to:

  • Stimulate tissue all over the body with frequency
  • Build strength and resilience throughout her musculoskeletal system.
  • Carefully track and record every training session to ensure progressive overload
  • Map out weekend walks and gradually build in more duration and elevation

Cardiovascular Fitness & Walking Progression

Alongside the Strength sessions, we built cardiovascular fitness gradually over a 3 month period.

We included:

  • Long weekend walks that increased in duration and elevation over time
  • Walking to the gym from work to accumulate more time on feet
  • Additional cardio before and after sessions when appropriate
  • Event specific preparation for the Yorkshire 3 Peaks challenge
  • Planned exposure to the actual course and environment

Event Day Simulations

As part of the preparation, we also carried out event day simulations, she practiced completing individual peaks while testing hydration, nutrition, and pacing strategies.

This allowed her to gain confidence in understanding:

  • How much fluid she would need to consume and potentially carry
  • Which food worked best on the day for fuelling long distance walking
  • How to manage energy levels throughout the day
  • Get familiar and comfortable with the terrain and routes

Results & Rewards

More than just weight loss. To celebrate her achievements, she received a £50 voucher for reaching her weight loss target and completing the Yorkshire 3 Peaks challenge.
