Cycling-Related Strength & Conditioning

Most people should be able to walk into a gym and deadlift BW during their first session, if taught correct technique. For example, I got my sister to lift 10xBW on her VERY FIRST deadlift session. Of course she only weighs 45kg, but for anyone around 70kg 1xBW with no prior training should be possible with the right cues. (Not that I recommend trying)

You are pre-calculating projected percentages of a BW deadlift? You should breeze past BW within a few sessions at most, even if you are old & creaky or training pretty hard in other activities.

So your sister lifter 450kg first time ever, I would get in touch with Roy Castle and Norris Mcwhirter then. But I suppose you mean 10 reps of 45kg.

Either way, a lot of this is misleading and incorrect, If you don't stop spouting such utter bullshit, I'm going to ban you from this forum.
