1. Track your cals rn at maintenance, this will help you cut later and get in the habit, do for 2-3 weeks 2. Eat 3 meals a day if you can (I maxed at 2 with lots of protein powder to make up for it) aim for 80-100g of protein a day 3. Lift heavy and 4-5 days a week, lift lighter 1-2 days and rest 1. Target wherever you want and ignore cardio 4. After about 16-17 weeks you should be able to come off the bulk and go back to your normal maintenance, may or may not need to cut from there
Disclaimer you will ofc gain weight while gaining muscle but if you start now you can bulk for a few months and have a perfectly healthy cut duration before next summer. Bulk and be slightly heavier in the winter and nobody will really know until you’re ripped in the summer. Godspeed sister
