slow in legs

what do i do if my legs are slow, i sit whenever im not sleeping

what u mean by slow? They grow slow? They move slow? They decay slow? They rot slow? They recover from workouts slow?

no agility

1) Interval training - Sprints
2) Tuck jumps
3) Go play soccer or basketball more often

But you will need strength to complement.

Go do more burpees and barbell squats.
