With training, there are many techniques that enable you to extend your
efforts, in attempt to promote a hypertrophic response. Drop sets, tri-sets,
giant sets, rest-pause sets are all examples of techniques that enable you to
push yourself beyond concentric failure with the hopes of building bigger,
stronger muscles, while burning off unwanted bodyfat. The only issue with many
of those techniques is that you have to rely on the equipment needed to be
available in the gym you are training at.
