Low sitstart with two horizontal holds as for Cross-Fit, climb the overhang, traverse to the left (two possibilities) and mantle up above the start of Burpees.
NB: the two possibilities in the traverse are reported as "Cross-Fit prolongé" and "Cross-Fit prolongé par le bas" on the drawings.
It is also possible to continue for 3m on the left after a total rest (same grade).
