Hello Silke, I believe I used 2 springs, I was using a balanced body reformer so it was probably a red and blue spring but I am not sure so far past the film time. a bit of advice: always test the spring tension before you set up the jump board as different reformers have different tensions and what is important is the right among of tension to allow for jumping with out being too light or too strong. You can feel it on your body.
Hi! I've just bought a reformer but my coach hasn't covered jumpboard work in our sessions. What would you recommend for those who don't have much ankle flexibility? Mine only really make it to 90 degrees, no less. I've worked through this video on my toes for most of it, but I don't want to be hurting myself or missing out on work.
