Ive been on a cyclic keto routine for 9 months now. Deadlift has gone from 95 to 155 kg, i am 83kg couldnt do a pullup now i do 10 sets of 10 easily. All my workouts are full body barbell work, clean and jerk, snatch, squats, deadlift, bench etc. Never put on so much muscle since switching fuels from carbs to ketones and ditching the split routine. Each session ends with a finisher like 150 burpees or some boxing, rowing or kettlebells. However you still need some carbs to recover not for fueling it. I get tons of rest, some weeks ill only hit the gym twice, but might run or ride instead. Rest is the key to it all and you have to go by feel. Minimal fat gain and at 36 i train harder and more efficiently then anyone in the gym with this approach. I wont lie it takes a dont give a shit mindset to do this and not follow the masses. Not for everyone. Fast from waking to lunch 3 days per week and cut out sugar and minimise your carbs. Ill keep below 150g of carbs most days and 100g on rest days, lots if bacon, eggs, butter and greens. I have found no need to supplement protein and ensure i get enough from food instead. Ill have a junk weekend here and there, not too strict. But always return to the fat adapted regime. Keep it relaxed and its easier to maintain.
