Sportinstituut Goederaad is a sports centre that has been well known in Voorschoten for more than sixty years. Its owner, Percy Rüben, offers you the following classes:

  • Conditietraining: a mixture of exercises on music to improve your endurance, flexibility, muscle power and body posture.
  • Aerobics: more intensive than ‘Conditietraining’ and with more emphasis on rhythmic movement.
  • Judo: Japanese martial arts class by Sensei Percy (4th Dan) in which both youth and adults learn to make throws, holds and other techniques. Furthermore, attention is paid to treating each other in a respectful manner.
  • Kickboksen: kickboxing classes for youth and adults. 
  • Taijiquan: sport based on ancient Chinese martial arts. Taijiquan is good for body and mind. It can have a positive effect on a variety of problems like rheumatic complaints, blood pressure, heart problems and stress.
  • Taekwon-Do: Korean martial arts class by Master Marco (7th Dan) comparable to Japanese Karate.
  • Seniorengym: exercises for senior citizens or others who prefer to exercise on a less intensive level. Seniorengym is a 45-minutes work-out in which all muscles and joints will be trained and your body condition improved.
  • Hatha yoga and stoelyoga: Hatha yoga is 'regular' yoga, stoelyoga is yoga in or using a chair, so no exercises on a yogamat. Yoga improves your strength, flexibility, posture and mental balance.

Weeshuis Don Bosco

Percy Rüben collects money for Orphanage Don Bosco in Surabaya in Indonesia since 1990. The reason he has chosen to support this charity is because his father stayed in this orphanage when he was young. This charity project has merged with the Pertolongan Foundation in 2014.
