I do fine on most everything else but on squat and deadlift my air or heart rate seems to be stopping me before I hit muscle failure unless I go really heavy like 1-2 reps. Just going light like 250 for 5 or 6 will set my heart to hammering like 150 bpm or so from rest.
I say hammering because I run and do cardio and I can comfortably maintain 155 for 10 minutes or longer and 145 for half an hour but something about the way it hits all of a sudden after squats or deadlifts feels different.
I am 38 about 235 right now and I have 20lbs of fat to lose. My max is probably 380 squat and 420 DL so I am not moving any serious weight. I don’t know what is going on it formatted this as one single line of text?
