I can outperform 90% of human trainers as well in the first 60 days of training as most human trainers are clueless and the novice effect is real.
Do any compound movement with as much weight as you can manage for a set of 5. Do a couple more sets. Add 10 pounds to the bar every subsequent workout until failure. Then add 5 pounds to the bar every workout subsequent to that.
That'll get most healthy young people through the first 8 weeks of training. Train two or three times a week and you'll add 80-100 pounds to every lift.
The caveat being that small people will run out of linear gains in their upper body during that time.
