Chris wants to improve his lower body strength. he can best do this by a) weighted squats, 10 repetitions each set, with longer resting time between sets b) weighted squats, 18 repetitions each set, with shorter resting time between sets c) unweighted squats, 10 repetitions each set, with shorter resting time between sets d) unweighted squats, 18 repetition each set, with longer resting time between each sets

a) weighted squats, 10 repetitions each set, with longer resting time between sets

Explanation:

To stimulate muscle strength, exercise should be done with some kind of weight. The weight promotes a greater effort of the muscle, stimulating its resistance. For this reason, we can say that if Chris wants to increase his strength in the lower body, he must do squats with weight.

In addition, Chris should increase the rest time between sets. This is because resting will cause Chris to avoid several injuries and will help his immune system to recover. In addition, during rest Chris's body will release various hormones that will help him gain lean mass and stimulate his muscle.
