1. You may try to add little weight by little. Make it be like 5 new pounds per week. Overall you will not notice a difference, and it won't make it much harder to train. But after a month you will already bench 220 lbs at least.
2. Deload a bit - if it has been a long time since you deloaded for the last time, your body may be exhausted, and it needs a good rest.
