Cardio before or after weights

I usually do 20 minutes of treadmill before starting my weight training but sometimes I feel tired even before lifting weights. Is it better to do cardio after weights

Bro I prefer doing cardio after my weight training

Do a little warmup before weights and save longer cardio for the end

I made this mistake and my lifting performance was getting affected

If your main goal is muscle building then try cardio after weights

Five minutes of light treadmill is enough for warming up

I do cardio on separate days sometimes

Try both and see which works better for you

Dont exhaust yourself before your main workout
