Too light to be that height, boyyyyy. Gain weight, do LP. Be aggressive about it. Lifts'll go up. Maybe a few months of progress, especially if you aim for 105kg bw as an end goal w/ 2kg bw gains a month. Do it.
I mean, you could keep doing TM, but meh. You're about the same height and weight as novices in my gym who just won't eat to gain weight. Their lifts have stalled a long long time ago. You won't get fat, so don't even worry about it. I know what fat and being fat is. Fat is not 100kg at 186cm. Trust me on that. Dew the programme.
