If you’ve been working the same lifts for a long time, it may be time to switch them up. Instead of flat bench do incline. Instead of overhead press with a bar, do single arm press with a dumbbell.
Everybody gets stale.
The good news is you’ve had tremendous progress in a month on your other lifts. Most feel lucky to get 5 lbs a month and you got 10 and in one case 25.
