I just went to my first Gym session doing weights- it was awesome! My flatmate who's super into weight lifting took me and taught me how to bench, squat and deadlift- managed to do the bar with him spotting me, so probably 15kg, and then used a 15kg weight for all the others.
Absolutely knackered now, but one of the trainers complimented my deadlift form, and said for a beginner I was really good! We're aiming to try and just get me doing everything a little bit now, and then as I progress switch to focussing on certain areas on different days.
