Enough-Best or Too Much-Too Bad?

i am 16, first of all, and in a dilemma. could i, on the same day, do tempo in the morning and speed work in the afternoon (some 12 hrs distant from each other). maybe 3 times a week and once only speed and the others passive rest or something like that. basically i want to get an ida if that could be done without me destroying myself. all of this being in season.

i don’t do weights cause of back problems and stuff and i wat to wait a year or so before i do weights and destroy my back because in 1 year time i’ll be naturaly stronger etc.

so i would like to know if i can opt to a lot of tempo and speed work without killing myself.

Thanks,
Keith

what back problems? You need to identify the problem, and progressionally strengthen it.

I dont fully understand the question or the situtaion, but if your thinking about doing both in the same day I would go with the speed work first and the tempo in the second workout.

could you continue this thread in the other thread good or too much pls, cause my pc was out of hand and i didn’t notice he had already posted it and all.

sry for the mistake,
thanks
