I have been in a strength gain rut for a spell as well as an overall flatness in my personal fitness goals.
So lately I have been changing my reps up with the weights. I'm still mostly doing a pyramid approach to the reps (10,8,6,4,2,8) when I do a primary exercise (bp, squat, military press, etc), but on the associated secondary exercises I've been doing 9's.
Instead of the obligatory 8 reps, I shoot for 9. What a difference that last couple weeks with just that minor change!!
I've also started doing windsprints on the bb court during and or after weight training and the strength in my legs has improved too.
So, the tip of the day is to not be afraid to mix things up periodically to break stagnation or boredom.
