I've been working out since a year. Recently, the program that I'm following is Starting Strength. My bodyweight: 58 kg. Now, the problem that I'm facing is whenever I go heavy, i.e squat: 66 kg, deadlift: 66 kg, bench: 51 kg, I fall sick.
I start suffering from sore throat, fatigue, strength reduction, viral infection, low motivation to workout, lastly, I don't feel like doing anything else since I'm so tired. I can tolerate muscle aches, but not CNS breakdown.
About my nutrition, I'm not following GOMAD, but LOMAD( litre of milk a day). I eat all veggies. Take in 1 g of protein per pound, through diet and protein shakes. I also take PostJYM as preworkout and postworkout.
How can I keep my immunity strong while lifting heavy? Your help would be really appreciated.
