change lifting routine every 8wks?
Just curious. I have been on a strict lifting schedule for 8weeks now. I do a 4day split, record everything I'm doing, and always up my weight if possible to keep my muscles working. I still experience muscle soreness after each workout. Is it wise to continue my routine and just keep challenging my muscles by upping my weights or should I change up the exercises all together? I've been looking online for different 4day split routines and most involve many of the exercises I'm already doing, so I'm not sure what other exercises to do if I don't do the ones I've been doing. For example if I work triceps and chest I will do four exercises for each muscle group, typically 4sets,each around 10-12reps. I rest very little between..maybe 30seconds so I keep my heart rate up. Thoughts?
