+Parkour_FRHVN Okay when you land the sideflip, keep your legs loose so you are kind of falling to the side. Then repeat that till you feel confident to stay tucked
When i do double sideflip i doa sideflip then i do 2 spins with a tuck i dont know wuts happening but its hard and by the way his double sideflips looks wierd
Destruction what help me was simply to look strait forward in the air and think like I'm rotating like a barrel. Sorry can't help much but that's what helped me.
