first, what are your goals? weight loss? strength/mass gain?
every 4-6 weeks, even if you keep the same basic routine, switch up exercises (Ex: on shoulder/chest/tri day, pick diff exercises that work the same muscle groups just in different ranges of motion so your body doesn't develop bad muscle memory). Meeting with a trainer is also a good idea so you can plot goals and watch your progression (weight loss/gain, monitoring body fat %, etc).
try lowering reps, upping the weight. When you can do the original reps comfortably with a higher weight, inc the weight, drop the reps again.
try describing your every day workout routine so we can get a better understanding of what exactly it is that you're doing. take us through your monday-friday routine. I'll give an example of what I've been doing the past few weeks.
Sun: pick a monthly challenge
Master Challenges Sticky
Mon: lift (legs,back,biceps)
Tues: rest
Wed: 2 hr grappling class
Thurs: 2 hr MMA class
Fri: rest
Sat: lift (chest, shoulders, triceps)
For lifting days I warmup with stretching and conditioning excercises (lunges, wall sits, pushups, etc) and finish the workout routine with 20-30 cardio (elliptical/erg/bike).
