Weight training program

[Radmir]

Hi guys,
Going to the gym about 3-5 days a week (taking whey protein). Set myself a goal to gain another 6-8 kg. At the moment trying to go into heavy weight training, however couldn’t get result (stopped at 66 kg).
Training program:
First day: Back + Biceps
Second day: Chest + Triceps
Third day: Legs
Fourth day: Shoulders + Arm (Biceps and Triceps)
Can somebody give really useful tips? If will like it, promise to try and post a result here. Thanks.

Too much bicep and tricep. you're going to some tricep work from press exercises and bicep work from row exercises, because those things have a residual effect.

So you could ditch the shoulder and arms day and just tag shoulders onto legs.

Then just do the 3 weights days every other day.

Also do the chest day first day and the back day 2 days later, so if there is any residual recovery of the chest happening, it won't affect the back.
