That is what I focus on in my dead lifts, maximizing explosive force for the bar to the top of the quads as quickly as possible, while making sure it "rams" solidly into my quads, via hip thrust
I have a 16KG kettlebell at home & 4kg kettebells too. My gym has tons of kettles.
Once a week or so I'll do Kettlebell swings with the 16s or 20s, that seems to be good for snap and velocity, and cardio :)
I'm older (52) so I do my strength training after cardio.
Kettlebell swings are great. I aspire to still be lifting when I am your age. I'm the underside of 40 (only just) - and want to build as much of a strength base as I can before I know it will decay. I walk 25 min to the gym, so that's my warmup & cool down. Only drive if raining.
