Why am i getting toned as im bulking?

it could be your not eating enough calories

or your not lifting heavy enough

you want to perform 4-6 reps

6-8 reps

an go heavy

also you need 20x your body weight from calories

1 gram of protein each pound u weigh

everybody has different body types... your more prone to being ripped

When bulking, the average person can only put 1-3lbs of pure muscle on their body per month. Since you gained 23lbs in 4 months you've gained about 4lbs per month (rounding). You aren't putting on that much fat which is a good thing. So you are probably eating quite healthily and not putting on too much fat.

When it comes to bulking people just add too much fat so it appears that they are not toning up but in reality its just the extra fat blocking the increase in definition. So when people cut the remove the excess fat to reveal the already ripped muscles they got from bulking.

However you do gain much more definition when increasing the amount of reps in your sets. Example: instead of 6-8 reps for mass gain, you switch it up to 12-15reps for definition)

You're toning because you had very little fat on you before you started bulking I'm guessing.
