@rbnfitness_: If your biceps aren’t growing… do THIS. 21s will expose EVERY weakness in your curl. 7 bottom 👉 7 top 👉 7 full reps. Controlled tempo, no swinging, no ego. If your arms aren’t responding, it’s probably because you’re not putting them under enough tension. #bicepworkout #armdaypump #musclebuildingtips

Bro are 21s actually good cuz I remember hearing ppl like AthleanX and shit talking about how 21s are really good then recently ppl like TNF and Jeff nippard and shit say 21s aren’t good because the main driver for hypertrophy is mechanical tension over a full ROM and now ur the first time I’ve seen someone do them again genuinely asking
