Frequently Asked Questions
Do I need to be flexible to do Kinstretch?
No! Kinstretch works for all levels, improving mobility and control from whichever level you are now.
What should I bring to class?
Just a towel will be enough! Good yogamats and water are provided but you are welcome to bring your own.
How is Kinstretch different from yoga or stretching?
Kinstretch uses a joint-specific training approach to strengthen their specific qualities and functions. It will feel more like training, because it is.
Will Kinstretch help with pain or injuries?
It definitely can, but remember: Kinstretch is not physiotherapy. If you have a serious injury, consult a physio. Your instructor will always check for injuries before each class so that movements can be modified for you.
Do you provide 1 on 1 Kinstretch training?
Absolutely, in a 1 on 1 setting we'll go through a detailed functional range assessment and dive deep into combining mobility and strength. Contact jim@strongsessions.com for availability.
