Background: I tore my pec benching about 6 years ago benching (I'm 43 y.o. now: 217bw, 5'10"). Per the Doc/MRI: Tendon was OK/intact. They said it was just the muscle and I didn't need surgery. I didn't know anything really about strength training or rehab then. After about a month layoff, I rehabbed it myself, doing real light chest exercises, reps of 20, etc. For about the last 5 years or so, I have avoided flat heavy normal grip benching. I would do heavy barbell incline presses instead . . .not feeling "safe" to try flat benching. I worked up to a 235 5x5 on inclines. I would only do close grip flat benches as an accessory.

Just Recently, last 2-3 months: I started a normal flat bench workout recently based on the TM program. I started off w/ 225 5x5 VD / 245x5rm ID. Real easy start, felt as if I was "leaving some on the table". I do really no other upper body accessory lifts, because I'm currently progressing just fine, and there's no time for anything else. I've worked up to a 255 5x5 VD / 270 5rm ID. The last few ID's I've been playing w/ 275 w/ 'easy' doubles and triples, preparing to try a 275 5rm.
No pain, tweaks, aches, nothing . . .just some minor DOMS after VD typically.

BUT, now I'm noticing a tender spot, in my 'dent' from the tear on my pec.
AND, I notice a small bruise about the size of nickle/quarter right at the same spot. I saw the bruise first, then starting pushing in there, I can feel the tenderness now.

Do think I should Stop and reset or what?(duh) Do I have a long term problem?
How careful should I be with this? Do tears re-tear at the same spot . . .

Any advice would be appreciated.
Mike
