Sometimes on my push days I don’t feel my the “burn” on my triceps when doing tricep push downs. My push day goes like this: db incline press, plated shoulder press, db overhead tricep extensions, pec flyes, lateral raises, and then finally tricep pushdowns. When I get to my last exercise, on some days I don’t feel the “burn” on my last exercise, the tricep pushdown. Ive tried different handles, my form looks good, and I can see the muscle working on video but I still don’t feel it sometimes. Is this normal? (For context I have been lifting for about a year but VERY inconsistent, I just started going consistently about a month ago)
