timshel saidI have been doing a full body routine for a few weeks. It takes me at least 90 minutes to complete and I do 10 mins of cardio beforehand to warm up. I do this 3-4x a week. On the off days I swim for 45 mins freestyle and breaststroke. That's my weekly routine.
Is it more beneficial to do isolated workouts on different days? What are pros and cons?
I'm afraid Paul is not quite right... the whole "avoid muscle" if you want to swim thing is not quite true. Your goals are key - what are you training for
Splits were introduced back in the mid C20 and only really became popular when roids came on the scene which enabled people to train 7 days a week and still recover at the systemic level. Splits were then used as individual muscle groups still needed to recover.
Therefore, if you are lifting 3-4 times a week, esp if it's 3, then you don't need splits. If you have lots of energy on the routine you do then leave it. If you are getting tired, then you need to rest more, which might mean splits.
