Man I can swing a hammer a few times at work and blow up like I just did bi's and tri's workout. Veins pop out. Lol. And yes I can tell with endurance too, worse sometimes than othersAre you getting the severe low back pumps from Tren yet? lol Also speaking of shitty endurance… I tried to mow my yard yesterday after working out and it about killed me. Lmfao, felt like a fan a marathon when I was done. Tren has destroyed my endurance.
