Legs = works buttox, quads, calves, hamstrings - and even sneaks some abs in there too!
Finisher = usually performed after another (traditionally heavier / weighted) leg workout to 'burn' the muscles you're focusing on (in this case, legs!)...and finishers also tend to kick start recovery processes.
Superset = alternating sets of two different exercises with no rest in between
do 𝐱𝟒 𝐫𝐨𝐮𝐧𝐝𝐬 of each superset (each of the two side-by-side moves) below with no rest
𝐫𝐞𝐬𝐭 𝟏𝟎-𝟏𝟓 𝐬𝐞𝐜𝐨𝐧𝐝𝐬 in between each superset
once you've completed all four rounds of the superset, 𝐫𝐞𝐬𝐭 𝟑𝟎-𝟔𝟎 𝐬𝐞𝐜𝐨𝐧𝐝𝐬
complete until you've done all four rounds of all four super sets
