How much speed gain?

how much speed can you gain doing tuff cuff religiously?

it depends.

my speed is 84 do you think a can take it up to 89 from now to january or february

What have you been doing in terms of exercising and nutrition? If you’ve never worked out before then following Tuff Cuff and simultaneously doing a weighted ball/long toss program will definitely help you reach your goals. Also, how old are you and what is your height and weight?

i have worked out the normal but never really dedicated to it. I dont really long toss a lot because of school and time.Im doing some weights not to heavy and running some times and i need to streghtengs my legs im 5 11 150
