I just started the intermediate version of Gant's hybrid program and am trying to come up with short and/or heavy WODs to fit the mold. Gant's guidance:
...short and intense. Keep it under 10 minutes (usually under 5). Keep it heavy, and keep it functional. Select workouts that require very little rest.
Two metcons I've done thus far:
Four rounds, individually for time:
5 x 65lb Dumbbell Snatch (each hand)
10 x 65lb Dumbbell Swing
Four rounds for time:
With weight vest
5 65lb DB Thrusters
If you have any WODs that fit this mold, please post 'em.
