Am I too little to be a firefighter?

Just as it says am I too little? I am a 20F weighing 118 pounds currently taking firefighter 1, however we have to pair up with partners to carry each others weight on the ladder and down the stairs. I accidentally got paired up with the heaviest person. I’m only 118 pounds and I’m paired up with the heaviest person at 220 pounds. Im currently working on my upper body strength though at the gym. I can only carry my body weight. I don’t think I’m gonna be able to carry them due to my physical inability. Is there anyway I can ask to switch my partner during these training sessions? I feel too little to do my job but I want to be a firefighter so badly. Is there anything I can do to make it easier? I desperately need some advice.

Also little backstory the reason I don’t have upper body strength is because I used to do dance so I ended up losing most of my strength. Is there anything I can do to make this easier?
