If you are going to another school they probably dont know a thing about you so u want to make a good impression 40 time is one of the best ways strength in the weight room doesnt always translate to the field but speed always does
I pla safety 4.9 is slow defintley set your goal for 4.7 or lower
Just running wont drop a thing off of your 40 time
I do my own 2 a days every day 20-30 min tops each time in the morn then in the evening
I do sprints in the morning ...
2X 100 yards
4X 60 yards
2X 60 yards interval (sprint 20 then jog 20 then sprint the rest)
The reasoning for the high number in yards is so you overtrain yorself so 40 yards is like nothing and you finsih strong
*start each sprint in your sprinters stance*!!!
At night I run stairs or hills take your pick if up and down is 1 time is 1 rep
then I do 4 sets of 3 reps The best stairs are stadium stairs or just find a steep hill
I did this last year and it brought my 40 down from a 5.1 to a 4.72 from begining of summer to the end
ALso to have a fast 40 you need a strong core and lower body abs quads and calves u said u were familiar with the weight room so i wont need to name exercises for this but alternate them legs then abs give urself the weekend to rest aswell
Plyometrics are good to do I put 2 of them on my legs days
1.
Start in a standing position then squat position (parallel) then explode up into a standing postition 3 sets 50X
2.
Start in a tucked position then explode up jumping as high as you can go
I have trouble explaining that 1 so here is a link
