The key is diet of course. But in regards to training I just lower the weight and increase the reps. I stick to 1 or 2 bodyparts each day. But always finish with cardio after weight training. I like to mix my cardio too. Meaning the machines I use each day and the techniques. Such as on the treadmill I will go up to a sprint and back down... up and down... or maybe other day use a incline and an more steady but decent pace till I can take no more. Much more intense techiniques are usually the best so do them more but variety is the spice of life.
If you train 5 days per week maybe do weight training 3 days and just cardio on the other 2. So something like Mon= Legs, shoulders and cardio. Tues= Cardio. Wed= Chest, Tri-ceps, cardio. Thurs= Cardio. Fri= Back, Bi-ceps and cardio. Do abs about 3 days per week and use when you do when you feel best.
There are so many ways and the above is 1 of thousand but it can be alittle awkward. You could be do one part each day with cardio afterwards. If you want to work on a certain part alittle more you could put that in twice but may sure there is a decent gap in between workouts (such as Mon and Thurs). So maybe something like-
Mon= Legs, and cardio
Tues= Shoulders and cardio
Wed= Arms and cardio
Thurs= Chest and cardio
Fri= Back and cardio
Abs about 3 times per week when you feel best doing them. They are just a few suggestions but my rec would be the following:
Mon= Legs, bi-ceps and cardio
Tues= Shoulders and cardio
Wed= Cardio
Thurs= Chest, tri-ceps and cardio
Fri= Back and cardio
Again do abs about 3 times weekly b4 cardio and after your other parts. You can even do some sets of abs on the w/e when at home.
I start my PCT soon and I think my routine will be something like the above. It's a good solid routine and if your diet is good and your actual techiniques and choice of exercises you will be cool. Hope it helps.
Oh my fav machine is the rowing machine - great to cut on and just overall health, look and flexibility.
