Thinking of hitting a test/var cycle this summer, but I am diligently restricting my caloric intake to stay cut during summer. Can substantial gains be made while drastically restricting calories?
Ok we have to first establish whether you are cutting during this cycle or staying cut. Quite different approaches.
If you are cut enough try this:'
Let's say you are a 200 pound dude at 10-12% bf
Lets say your basal metabolic rate is 2200, assuming mid-high activity levels on the Harriet-Bennet equation, your daily calorie intake should be 2200x1.6= 3520 Kcal a day.
For the first 3 weeks you keep your Kcals at 3000 a day, get over 300 grams of protein and stick to a High protein, mid fat, low carbs diet. Can even do carb cycling, whichever you prefer
For weeks 3-7, you do a refeed 2 week mini bulk. Kcals at 4000 a day, over 300 grams of protein, introduce more carbs during peri-workout period. If you are on Test E and vars, week 3 you start to peak and things start getting real interesting. So lift heavy and intense.
For weeks 8-12 Maintain your Kcal at 3520Kcal as calculated from when you begun the cycle. You would now have substantially increased lbm with minimal fat gain. Here, you are actually on a slight Kcal deficit as you have more lean muscle and that requires more Kcal. You will lean out quite a bit more without sacrificing strength and hardness gains.
USE an AI, it will help with oestrogen sides that comes with Test and you will ge bloated like a water ballon. Also watch your sodium and drink over 1 Gallon of water a day
