And you thought bobsleigh was all about a little pushing, a little sliding?
Look at Canada's best female bobsledder – the world's best – Kaillie Humphries do this.
Checking in at 1,70 m and 77 kilos, Humphries back-squats 150 kilos.
Here she is showing off some of her lifting routines.
Among them are "power cleans" - an Olympic weightlifting move, with 200-pound weights. Humphries said it's good for explosive forward thrust movements, and about getting it going from a static position as quickly you can.
She added that a lot of what they do is low volume - sets of 1-2-3 repetitions at maximum weight.
For agility, Humphries uses 25-pound weights, thrown and caught about 20 times, which activates the core.
Humphries, 28, goes into the Sochi Olympics on a roll, having won her second straight women's World Cup bobsleigh overall title in Germany just last week.
Had Humphries — the Olympic champion and now a two-time overall World Cup winner — gone 0.03 second slower in that final race, American Elana Meyers would have won the overall title.
Maybe that was because of an extra 10-15 reps in the gym, on any given day.
A huge favorite for the top step of the podium in Sochi, Humphries and brakeman (brakewoman?) Heather Moyse won gold together at the 2010 Games in Vancouver.
