BUILD is a favorite! Low impact, high strength is the theme and "apartment friendly" for those who do not want to leave the ground (no jumping). You definitely need a set of dumbbells for this one as it works through a lot of strength based exercises including: front squats, bent rows, cleans, side lunges, chest flys, reverse lunges, curl to press. You can expect to have a bunch of different options throughout the whole workout and modifications and progressions are provided.
