I have been into bodyweight/calisthenichs training for 1 year now. After working on basic exercises (+30 pull ups/+40 dips/50 pushups/10ish handstand pushups to wall), I decided to start training for skills like planche and front lever.
After learning how to front lever (I can actually hold 10+ sec of full front lever), I decide to start working for the planche. After a while I realized that my main problem is the lack of activations in the abdominal part,probably caused by the executions of the planche in the propaedeutics (mainly tuck planche).
Do you have any exercises to learn correct activation of the abdominal area in the planche? Are there any specific exercises to train the core for the planche?
For the moment, the only exercise that I feel lightly in my abdominal area is the famous "Planche lean", should it be effective for the abdominal?
