Another important part of form is using a full range of motion while doing the exercise, meaning you do not stop your bench press half way down. If you cannot complete the full range of motion you are probably using too heavy of a weight. Your motion should also be slow and controlled, avoiding jerking the weights, swinging the weights to get momentum, or bouncing the weights.
Muscle soreness is a common side effect to working out. It subsides as part of the recovery process. Delayed-onset muscle soreness is the most common type of soreness and occurs 24-72 hours after training. This is why rest days are important, to allow soreness to disappear before training again. In fact, if you are scheduled to train and are still sore, take an extra day off.
My advice is to get them removed from a dermatologist if any of them stand out that much they look like a nuisance. Now, small moles will always get darker as the level of melanin in your skin increases, this is definitely more prevalent with guys who use melatonin 2, that shit actually gave me new moles when I tried it and I swore it off for good. I would just develop a good base tan and then tan once/wk to maintain it. That is what I do MOST of the year, once you get the base just do a maintenance deal once/wk. Once/wk in a tanning bed isn;t giving anyone skin cancer that wasn’t going to get it anyways, you feel me?
After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
