best way to warm up?

what do u think is the best way to warm up before you begin to workout?

biking?
jumping jacks?
running?
jump rope?
or anything esle that you do to warm up before a workout

I run on the treadmill for 10-15min or jump rope, at a quick pace though.

Generally begin with a light jog.

Then high knees, butt kicks, frankensteins, mountain climbers.
Then do static stretch the hip flexors and a glute activation stuff.

i just stretch 8)

Same, I just stretch before I lift, and usually some light bodyweight stuff that pertains to the bodypart I’m going to hit that day. Ex. Pushups for chest day, wide grip pullups for back day
