karate fighter needing advice

[kyokufighter]

hi i am yakibi, i am a karate fighter (kyokushin) and am hoping to compete in very near future. i have not done much with weights really most of my stuff is pushups on the knuckIes, situps, squats with no weight, puIIups, and those kinds of things. i weigh 83kg and want to be 100kg someday so i wanted to do more with weights and started 3 months ago. right now i started bench, squats, dead lifts, cleans, presses, and pullups but i get so sore i do not feel like training. my lower back get very sore and stiff too despite stretching it is main cause. the other day i do 155kg for 5 reps in the dead lift, not very hard but later my back is sore. my dad's friend say it from the muscles, not from me injuring it. i like the dead lift and want to keep doing it, but it make me too sore, any way to avoid this? also any good advice for karate fighters? kyokushin is very tough style, you must be able to take a lot of punishment and fight long time, so any advice i can get i thank you. right now i do some weights, pushups, situps, jump rope, and hit the bags. i need to run more for my stamina, i only do 5k three times a week.

Look into foam rollers and contrast showering to reduce muscle soreness.

If you are that sore, do less and acclimate yourself first before busting ass to the point of extreme soreness.
