Check another video of Alan Thrall about deadlift and body types.
Our deadlift form may not be a problem as long as we keep our backs flat.
Simply lighten the weight, use plates under the bar and film yourself to see if you’re good or not.
Back rounding was a problem I wasn’t realizing until I filmed myself.
Now I’m filming every deadlift training to see if I’m right.
I squat 175kgs and deadlift 200 conventionnal, pulled 210 once with relatively bad sumo technique lol
Concerning squats, as said above, safety bar, front squats are good weapons, I think paused squats helped me too.
