These are general goals for strength:
Back squat: 1.75-2x your body weight
Deadlift: 2-2.5x your body weight
Front squat: 1-1.5x your body weight
Overhead squat: 1x your body weight
Power clean: 1.25-1.5x your body weight
Power snatch: 1x your body weight
The bad news: the general consensus is that a man’s testosterone level starts to decline by ~1% per year after he passes 30, and muscle tissue is lost at the rate of ~3%-8% each decade for people who don’t perform resistance training
You’re getting slower and weaker: Type 2 (fast twitch) muscles starts to decrease faster than Type 1, so power/speed is the first thing to go (which is why it’s so important to train)
Get your shit together: The effects of sleep/nutrition/alcohol become more pronounced (it’s impossible to ‘work off’ a bad diet or excess alcohol consumption)
Less is better: To avoid muscle loss, perform multiple-joint exercises supplemented with single-joint exercises that cumulatively address all of the major muscle groups 2 or 3 nonconsecutive days per week
