But there's science behind this buzzkill. The rectus abdominis — the muscle that makes the stomach look defined as hell — is typically covered by fat (because that's how humans are made) and isn't affected by things like crunches and planks. "You can work your abs all you want, but if you have a layer of fat over them, the 'pack' can’t be seen," Ball says. And FWIW, that's not a bad thing or something to feel bad about. "It’s very unrealistic for most people to have body fat percentages low enough to see the abs."
A common belief in bodybuilding is that a beginner can make progress lifting rocks. This is not to offend the brutally huge strongmen you see on the MET-Rx World’s Strongest Men on ESPN who lift those 350-lb. Atlas Stones but is to emphasize the point that beginners can make progress on just about any program, using just about anything for resistance, even small Flinstone pebbles. But just because beginners can have success with minimal effort and nonspecific workouts, this doesn’t mean that their training protocol will also work for an experienced athlete, or for someone who wants to go even beyond a “slightly visible” 6-Pack!
A. I’ll be honest, building muscle as a vegetarian is hard. There are nearly no clean sources of protein in a vegetarian diet. Soya Chunks come close but I’d recommend you stay away from a lot of soya if you’re a male due to it’s high oestrogen content. You can try incorporating more Beans (especially Rajma), Chickpeas, Hummus, Lentils (Dal), Sprouts, Tofu, Milk, Cottage Cheese (Paneer) and Cheese into your daily foods. Unfortunately, all of these foods either have higher carb content or higher fat content as compared to their protein content. Stick to the low fat or ‘made from cow milk’ variants.
