Mixing it up

[Hockey Playa]

Im currently doing the 3-day split, working 2-3 muscle groups per workout. Ive been doing this for about 3 months, i was wondering if it was appropriate to switch up the muscle groups worked ex. Old- Lower body, Biceps New- Lower body, tri's. Does it even matter if i switch it up? would it be more benefitial jsut to switch up the actual exercises. I heard it was good to keep your body guessing during workouts, so thats why im asking this question, how often should you swtich things up

If you're gaining weight and/or increasing lifting numbers, don't change things up.

i second that. mix things up only if you're sure you're stalled.
