Sit Ups DO NOT = Speed

[kjamesmorris]

so stop doing sit ups and run more and jump rope with one foot

[Manuelcr7]

sit ups with heaviest weights are excellent for core strenght.

Rope skipping is to easy. It can'T biuld a strong core. You need isometric press exercisese and heavyweight exercises like a one leg Deadlift and one leg kable knee drives. or hip thrusts

@Manuelcr7 have you tried jump rope with ankle weights gets crazy tough

[Manuelcr7]

@j111oncher sry your speed skills seem to be very low. jump rope with ankle weights...what a bullsh..

it's a cardio and cardio kills speed!

if you want to run faster do high intensity and low volume plyometrics.

Plyometrics = simple the best

informative about how your muscles work, but jump rope isn't going to make u fast by itself.
