JS-treeni

JS-Treeni is a fitness and wellbeing service led by Jarkko Sakari Honkanen, a physical activity adviser and personal trainer from Lappeenranta, Finland. The brand offers varied ways to become more active, with an emphasis on helping each person find an enjoyable form of exercise and develop their own motivation. Services include exercise guidance, personal training, mobility training, and fitness and mobility testing. JS-Treeni also provides self-defence and fitness-combat training, alongside the JS combat gym.

Honkanen was born in 1982 and has been involved in sports throughout his life, participating in a range of physical activities. He has also worked as a martial arts instructor for approximately 20 years and founded two martial arts clubs in Lappeenranta. This experience informs the brand’s broad approach to movement and training. JS-Treeni recognises that no single activity suits everyone, and aims to offer options that make exercise approachable, practical, and enjoyable for different preferences. Customers can contact Honkanen directly by email or phone for information about the services.
