Some people take supplements together, but they adjust the amounts of each component. It is much better for you to tailor the supplements that are aligned with your preference and goals. It is also recommended you consult a health professional if you plan to do this.
Crunches won't build abs. Bench press is not the best for hypertrophy but for strength. Squats won't make you r legs shredded, just bigger. Training triceps is more important than biceps if you want massive arms. I agree with the last one.
