if i weight train with jennifer in the morning and jog in the afternoon and do it 4 times a week, will it hinder my progress because i train 8 times a week.
or endurance and weight training is different category?
I will echo Bantry's recommendation.
To give a more pointed answer to your question: endrance and strength training train different abilities, as the names suggest. So the training schedule you describe won't hinder anything.
That said, it won't benefit you, either. Ideal is three each per week. Most points you can get right now for endurance is three, which you can get from just three sessions.
For strength, 3 sessions a week w/Jennifer is also ideal (for up to 9 points total), until you get to Strength level 8. After that, you need 12 points to level up, and you can get that from either additional training sessions *or* from spotting girls on the bench press. For at least two reasons, I recommend the latter.
The only times it is worthwhile to get massages to get in additional training sessions is:
1) During that first weekend, so that you can get a point in Strength and a training point towards endurance by day 3, and
2) In cases where you somehow let yourself get behind your schedule and need to catch up before the weekend.
All that said, again, check out that Companion Guide.
