"According to Dos Remedios, getting jacked is a by-product of sound performance-style training. "I've got a newsflash for all the skinny dudes who flex their nuts on the leg press: I've seen chicks do reps with 700 pounds. How bad-ass do you feel about your 10 plates now?"
His advice: Avoid leg presses, Smith machine squats, and anything else that doesn't use your muscles in a way that resembles athletic movement, or that has no obvious transfer to sports performance. Choose squats, deadlifts, cleans, lunges, and step-ups over exercises that involve sitting in a machine with your back, ankles, and/or feet braced against pads."
