I've been working on my front splits daily since the start of the year and it's been going well, I've just sat into the splits and let my body weight do the work daily. I've now got to a point where my front calf is touching the floor, which is great, but it also adds extra friction I have to work against. I don't know if that's the main reason, but overall it feels like my body weight isn't enough to extend my range any further. Is there any way I can gently increase the downward force, or reduce friction if any of you suspect that is the problem? Maybe putting my ankle on a roller or something? Thank you!
