This is a very quick synopsis of the results and discussion. Writing a conclusion involves summing up the paper and giving a very brief description of the results, although you should not go into too much detail about this.
But doing both the squat and lunge in the same workout can be brutal. Instead, try doing the squat for 3 or 4 weeks, and then swap it out for the lunge in the following 3 or 4 weeks of training. Do 3 sets of 6 to 8 repetitions. Then you can try including both exercises in your leg workout, but scale back your sets. Do 2 sets of 6 to 8 reps of each move. Squat first, and then lunge.
You simply need to include squats and deadlifts in your workouts a few times a week. Of course, even the very best flat-stomach workout isn't going to do much for you if those nice muscles you build are covered with a layer of nature's comfortable camouflage -- a.k.a. fat.
