I've been doing some kettlebell swings (32 kg Towel Swing) just for 3 training sessions and I found that my back lever feels a lot easier now, I also tried some advanced pseudo planche pu and could raise my toes from the ground for a few seconds with strength, not with hop.
I wonder if anyone could share the experiences they had with this exercise.
I feel it is a great supplemental exercise for gymnastics, because the movement also resembles a jump.
I remember that Coach Sommer also wrote about one of his athletes, who got benefits in his planche training from doing swings with a dumbbell.
