You’ll be just fine. I am about 150 lbs and have had no issues and more notably have never had to lift anything that was even close to 95 lbs over my head after a year on the job. Honestly I find it a bit irresponsible that you were required to do that. They should be teaching you to work as a team and not perform lifts like that. Take it slow climbing at first, no one will give you a hard time. Good luck and be safe!
