I'm finding it hard to give up weights, but I have went from 10 workouts to eight, and it's just thrusts, dumbbell overhead press, core rows, wrist curls, dumbbell bench press, dumbell decline bench press, dumbbell incline bench press, tricep extensions.
My dumbells are only 8.5 kg except for the one I use for wrist curls and tricep extensions, that one's only 6kg, I use a bar for thrusts only and that's only 23 kg.
It requires effort but not a vigorous effort. I only managed to do three tabata workouts. Dide 8 count body builders, this workout where you go into plank, from plank in to classic pushup position, then back into plank, then into a close hand pushup position, then back into plank (great burining feeling in the abs) and finished of with some mountain climbers.
So 12 minutes.
