Hi,

When training I generally stick to 3 different exercises for each area. e.g on the biceps do 3 x 10 reps dumbell curls, 3 x 10 reps barbell curls and 3 x 10 reps pull ups. However on some occasions when ive got time left I could perhaps squeeze another exercise in, (although possibly not complete the full 3 due to saturation)  would this be overdoing it? can we do too many different exercises on the same muscle group in one session?

 Also when you reach saturation in, say,  dumbell curls in the 3rd set is it beneficial to drop the weight and squeeze a few more reps out?

Any advice welcomed.

The short answer is yes, you can do too much for a muscle, particularly small ones like biceps and triceps - they respond best to short sharp workouts.  You'd be much better upping your intensity, working to exhaustion on a few sets, and knowing that there's no way you could even think about doing another set!

 How many reps you do depends on your goal - size, strength, or endurance?

I'd always try and squeeze out a few extra reps - that's the part that really helps you to grow.

Hay there's a simple answer to this, do you know yourself.....My set routine on a arm workout give a high amount of sets with a counter play of 10 reps on average, but that all depends on the buzz.  Yes you can do to much but again it all stands on this (what are you training for) as you know, personal needs vary, a bodybuilder would generate 4/5 different motions on any given body part (sometimes more....buzz).

Doing drop sets are all good but not necessary all the time.  Muscles are strange things punish them and they will love you for ever, torture them, they will die.

I'm no body builder, but i'd say know yourself - at rthe end of the workout, do you feel like you've done yourself justice?

Sounds like you need to mix it up more - 25 reps at a low weight, 4 or 5 reps at a big weight, really work the muscle.
