yes, cutting carbs will lower your blood glucose. if you mush a bunch of sugars together, you get a carb. so it takes longer to digest a carb, because your body has to break it up first, but end result is still glucose in your blood, it just takes longer to get there (which is good, big energy spikes => fat storage, because you cant use it all in time).
unfortunately, you cant selectively lose fat, it all comes off your body together. the body has fat storage preference, and they are:
men: belly and chest (man-boobs)
women: belly, hips and glutes
that means that these are the last places you will lose your fat from, and unfortunately there isnt a way to change this.
So I do, Back and Biceps, Chest and Triceps, Legs and Abs.
this depends on how long youve been training for. this sounds really good for a beginner, but i dont know how long youve been doing this for.
to know what to train with what, you need to understand the functions of the muscles.
Back+biceps is great because: the function of lats is shoulder extension (pulling the humerus closer the trunk). the function of biceps is elbow flexion (and forearm supination). almost all back excercises involve some degree of elbow flexion, so that means your biceps will inevitably be worked if you do back, so finishing off a back day with your biceps is great. its the same with chest/triceps, chest pushes from the shoulder (internal shoulder rotation) and triceps push from the elbow (elbow extension), so thats a great combo to work together.
this means you should train all back, then all biceps, or all chest, then all triceps. take for example, bench press. its a compound movement, that uses chest, delts, and triceps. of the three, chest is the largest muscle, ie. it will fail LAST. so when you bench press cos you want a bigger chest, think about it - the muscle that you want to grow is not the muscle which will fail first. when you get to your last rep, and you just CANT push it anymore, which muscle will hurt the most? it wont be your chest, thats the biggest, its going to be your triceps (or delts if you have bad form). so would you then go and train triceps first? OH HELL NO!! (lol). what you would do, is pick an isolation excercise for chest, and do that before your bench press, so when you go and bench press, your chest is only at half its strength. thats why my working bench press sets are only like, 50kgs. (this is where its important to know the difference between body building and powerlifting)
legs are massive, and can make you throw up and feel sick for an hour after if you push to your max. as such, i dont train abs with legs because i physically cant, but if you pull and push and workout everything else, core strength is developed without you trying. train abs on your lightest day.
the only thing i would change, is to throw in some shoulders. i neglected shoulders at the start and im paying for it now.
