Hey guys, im new at this thing and need a little help. Been lifting for about a month. When i went the first few days i felt sore the next day but i dont anymore. Ive been doing about 6 sets of each exercise and on the last couple reps of the last few sets im struggling but on the first three sets its pretty easy all reps.. should i start with more weight at the start of the sets and reduce it as i go on? Any guidance is nice, i want to get bigger and i finally have time and money to invest in it.
