no one in real life cares what you lift, they only care about how you look...
I had some daft twat telling me last night his mate benches 200 kilos, I told him I bench 60 kilos, he didn't believe me of course because I looked better than his fat buffoon of a mate.
it depends what u feel like matters
400 pound bench yes thats impressive one rep
its very difficult to compare apples n oranges, a 400 pound 1rm max may equate to benching a total of 112,000 pounds per week wich is all his reps and poundages he lifted that week for chest hypothetically
in theory he may or may not be able to complete 33% more workload if he took 6 days off from chest and tried a monster chest workout totaling 145,000 pounds
in theory he may or may not get stronger this way
