Strength & Conditioning


Since the inception of the WimX Academy in 2005, Strength & Conditioning has played a vital part in player development. WimX believes that individual S&C training, tracking, planning and testing is a vital part to any serious player’s journey. Group training is good, but tennis is an individual sport where players have individual needs. That’s why WimX work hard to subsidise S&C training for serious players.

WimX S&C services are also available to external players.

Program Aims and Objectives

The S&C program, in consultation with the Tennis Team, has several aims and objectives:
  • To create athletes, who are self-sufficient & independent
  • To provide bespoke programs to cater for individual players’ needs based on many factors, including: performance testing, movement screening, maturation status, training history, & injury history
  • To take a multi-disciplinary approach, which can include nutrition, psychology & injury rehabilitation
  • To offer tournament support from S&C coaches

Long Term Athlete Development

Player programs are based upon athletes’ biological age not chronological age, to account for the differences in growth rates and timings. Biological age is predicted using non-invasive measures, which are then fed into a predictive equation which also predicts; adult height, age of main growth spurt and whether the player is an early or late developer  (this method can predict adult height within ±5.35 cm 95% of the time in boys and ±6.81 cm 95% of the time in girls [Sherar, et al, 2005]).

Once biological age has been established, programs are guided using a modified version of the ‘The Youth Physical Development Model’ (Lloyd & Oliver, 2012). The youth physical development model provides a logical & evidence-based approach to the systematic development of physical performance in young athletes.

Fitness Assessment

The compulsory tests (performance testing & movement screening) are performed three times a season on all WimX athletes. Athletes are assessed on return from the summer holidays, after the February half-term break (after players completed first training cycle), & before the summer holidays.

Performance testing (compulsory)

The physical performance tests are designed to assess for all physical components of tennis (linear speed, multi-directional speed, lower/upper limb power, agility & anaerobic endurance) & are based around the LTA Talent ID physical testing.

These tests are performed on the athletes up until the age of 12 years old, after which they move on to a more comprehensive assessment. All results from the tests are compared to national averages provided by the LTA, which in turn are used to identify strengths/weaknesses and guide the program development. Players are issued a report after each testing period, which includes goals for the next training cycle. Goals are reassessed after each testing period.

Movement Screening (compulsory)

For this we use a modified version of Gray Cooks Functional Movement Screen (FMS). We have chosen this:

  • The FMS looks at how the body works as a whole to determine a general level of mobility and stability incorporated with functional movement.
  • Helps to bring attention to any asymmetries or dysfunction that may be present.
  • To rule out and red flag any special evaluation needs that may need to be referred to a physiotherapist or doctor prior to training.
  • Can be used to predict susceptibility to injury.

Once players have been screened, they will be given individual corrective exercises in which to incorporate into their warm up & cool downs.


Athletes are monitored for fatigue; session by session using a child adapted omni scale & adult version for senior players. Growth development is measured on a monthly basis. Club injuries reports are produced twice a season.

Older athletes have the option of more rigorous testing and screening procedures. Alongside the standard Functional Movement Screening conducted, there are optional extras, which include:

  • University of East London Performance Testing – which includes tests such as: body composition, aerobic endurance (treadmill V02 max test), lower body power (Wingate test), lower limb asymmetry (Isokinetic Dynamometry), and co-ordination (using a BATAK Pro).
  • Body Profiling
  • Postural Assessment
  • Sessional Fatigue Monitoring
