Eggs and glute bridges: 186 mg of cholesterol and why that stopped mattering

One large egg contains 186 mg of cholesterol, 6.3 g of protein and 72 calories, according to USDA FoodData Central. For decades the recommendation was to stay under 300 mg of dietary cholesterol a day, which made two eggs a borderline decision.

That limit is gone. The 2015 Dietary Guidelines Advisory Committee did not carry forward the 300 mg cap, citing insufficient evidence linking dietary cholesterol intake to blood cholesterol levels in the general population. The old idea that cholesterol you eat becomes cholesterol in your arteries in any direct way was a reasonable hypothesis that did not hold up in the data.

So the standard defense of eggs has become the standard position. Which is progress, and also a place where the popular telling overcorrects.

the nuance the egg industry skips

The American Heart Association published a science advisory in 2019 that declined to set a numerical cholesterol limit while still recommending a dietary pattern that minimizes cholesterol intake. Their reasoning is worth understanding: cholesterol response to diet varies substantially between individuals. A meaningful subset of people, sometimes called hyper-responders, do show measurable LDL increases from dietary cholesterol. Population averages hide them.

There is also a specific caveat for people with type 2 diabetes, where several cohort studies have found associations between higher egg intake and cardiovascular risk that do not appear in people without diabetes. The evidence there is observational and contested, which is exactly why a blanket “eggs are fine for everyone” is as unsupported as the old blanket warning was.

For a healthy person who trains regularly, eating eggs daily is well supported by the current evidence. That is not the same claim as eggs being risk free for every person in every metabolic state, and anyone with a lipid problem should be talking to their own clinician rather than reading a blog.

what an egg is actually good for

Vitamin D is the underrated part. One large egg supplies about 1.1 mcg, or 44 IU, which is roughly 6 percent of the daily value according to the NIH Office of Dietary Supplements. That is not a large amount, but very few foods contain vitamin D at all outside of fatty fish and fortified dairy, so eggs are one of the few natural sources in an ordinary diet.

Choline is the more significant contribution. One large egg carries about 147 mg, and the adequate intake for adult women is 425 mg per day, which most people do not reach. Eggs are among the densest available sources.

On protein, be realistic about the number. 6.3 g per egg means a two egg breakfast gives you about 13 g. The research on maximizing muscle protein synthesis per meal generally points to roughly 20 to 40 g of high quality protein. So two eggs is a partial dose. Three eggs, or two eggs plus Greek yogurt, or eggs plus cottage cheese in the mix, gets you there.

Egg protein is unusually high quality in amino acid terms, which is why it was historically the reference standard against which other proteins were scored. The issue is quantity per unit, not quality.

the bridge, done properly

The glute bridge is the most commonly prescribed and most commonly mis-executed hip extension exercise. Most people perform it as a lumbar extension and feel it in their lower back and hamstrings rather than their glutes.

Lie on your back, heels roughly 12 to 16 inches from your glutes, knees bent. Before you lift anything, tuck your pelvis slightly, meaning flatten your lower back toward the floor. Then drive through your heels and lift your hips until your torso and thighs form a straight line.

Stop there. The instruction to go “as high as you can” is the source of most of the problem, because once your hips are in line with your torso, further height comes from arching your lumbar spine rather than extending your hip. The end position should look like a plank tilted, not a bridge with a hollow in it.

Squeeze at the top for one to two seconds. Hold time matters more here than in most exercises because bodyweight provides so little resistance that the mechanical tension has to come from somewhere, and a deliberate contraction is what supplies it.

where the standard prescription falls short

Three sets of twenty is the usual recommendation and it is a poor one if you train regularly. If you can do twenty bodyweight bridges, the exercise has stopped being strength work and become an activation drill. That is a legitimate use, but do not expect it to build anything.

The 2015 study by Bret Contreras and colleagues in the Journal of Applied Biomechanics recorded mean upper gluteus maximus EMG of 69.5 percent of maximum voluntary contraction for the barbell hip thrust against 29.4 percent for the back squat. The loaded version of this movement pattern generates very high glute activity. The unloaded floor bridge does not come close.

The progression is straightforward. Move from two legs to one leg, which roughly doubles the load per side. Then elevate your shoulders onto a bench, which increases the range of motion at the hip. Then add external load, a dumbbell or a plate across the hips, and work in the 8 to 12 rep range where the last two reps are genuinely difficult.

If your hamstrings cramp instead of your glutes contracting, your heels are usually too far from your body. Walk them in a few inches. If your lower back is doing the work, you are almost certainly finishing too high.
