I've reached a couple of PBs in the last couple of weeks, after 10 months of once a week with a PT, and Pump classes & running in between (plus Pilates & yoga & dance classes).
I can now deadlift 85kg
Squat 50kg
And last week, in my deadlift session, I did a series of warm up sets at 40 & 50kg, then 3 sets of 5 reps at 70kg.
My trainer pointed out that a couple of months ago, 70k was my PB at 1 rep. Now I can do 3 sets of 5 reps.
It's kind of magic, really!
(I'm 59, weight 70kg & am 166cm tall).
A friend sent me a clip of Dr Catherine Walters, who deadlifts 105kg at age 70 or so. Wow!
I want to be her.
