[mesayseo]

are ankle weights safe to use to run with to get a faster 40
and what plyometrics are best to use.

[arya202]

use a weight vest instead.

weighted vest. ankle weights are horrible on your ankles... Box jumps. Shuttle runs. Lunges, work on your first 10 yds on your take off, then run 20's... then 50's. That's what I did playing football. Anything explosive.
