Wow. That is a lot of ... work.Squats with weights.
Dumbell lunges.
Dead leg lifts.
Focus mainly on the weight, (except with the leg lifts, because you want to keep a straight form), because you want to tire out at about 10-12 reps, which means you have enough weight to bulk up. Three sets of each. Rest (march in place or stretch), about 40 secs or so between sets.
And - eat clean.
