It all depend on what equipment you prefer and how heavy you want to push yourself. Dumbbell light to moderately heavy. If you want to get heavier than o 40kg/More than 85 pound at home, You will need a barbell, weighted vest and and eventually a squat rack. I love the weighted vest cause it is very handy.
This is for home exercisers. In the gym it's another story!
all the very best with STS,
