I'm not sure if this is the right place to ask this question, but I'm wondering if there is a lower end weight limit? My son is 5'9" and 125 and he is worried that he is underweight. He's been using protein powder and lifting weights and is actually up from 110 pounds less than a year ago. He just took the CFA and got the following results:
pullups - 14
pushups - 57
situps - 72
shuttle run - 8.8 s
mile run - 6 min 19 sec
BB throw - 68"
