I have been training sprinting for almost 5 months now and 5motnhs ago i checked it was 2.10m now its just increased to 2.10m to max 2.15m ... idk how my squat numbers have gone up (i can squat 1x my bodyweight ) .. should i just quit ... btw my form is okay while doing broad jump

I’m 37, 182cm and 90kg, with a bodybuilding and strength-training background. I’ve only done around 5–6 proper sprint sessions so far, with PBs of 26.50 for 200m and 60.87 for 400m.
For those with experience in masters sprinting, how have you found developing as a sprinter when starting later in life? I’m planning to do two dedicated sprint sessions per week and would be interested to hear about the progress adult beginners have made over their first 6–12 months, particularly those coming from a strength-training background.
