I have been struggling in these 2 areas for size lately and any tips or ideal lifts you guys would consider would be greatly appreciated.
Its mostly my lower chest that needs help, but my upper chest could use some work too.
and for my lats, im struggling to really get that spread im looking for.
For back, make sure you're working the pulldown function of the lats as well as the rowing function. After warming up on a pulldown machine, I like starting my back routine with pullups. Sometimes I'll just shoot for a total number of reps, but I've also had good results from just doing 4-5 sets. The trick here is to use the fullest possible range of motion. Pullups are one of the most popular exercises for poor form that I've ever seen. A good way to do them is to use a grip that when at the peak of the movement your forearms will be perpendicular to the floor. You want your forearms to at least be perpendicular; you can go as wide as practicable. Obviously going too wide can cause problems, so often I'll just switch my grip up to keep things varied. Start with a full stretch, then pull yourself up without kicking your legs or anything to give you momentum. It should be a fluid straight up and down motion. Your shoulder girdle will be moving down and back. Keep your elbows slightly flared out rather than tucking them in. Pull yourself up as far as you'll go, then lower yourself to a full stretch. Trust me, 5 full range of motion pullups will do more for you than 15 poor form pullups. Switch things up by doing them behind the back sometimes (harder and stricter) or doing close grip pullups using a V-bar. Add weight to increase intensity but not to the point where it hurts your form.
All kinds of rows! The bread and butter of a good back routine will be a heavy rowing movement. I'm fond of bent-over barbell rows. Lately I've been doing them with an underhand grip, which makes the biceps do even more work. Underhand bent rows are one of the best exercises I've found for biceps mass and strength. Seated cable rows and T-bar rows are also great rowing movements. If you want to incorporate deadlifts, I'd recommend doing them at the end of your back routine. This way, you're already good and warmed up (CNS is warmed up) so they'll be a safer exercise (providing your form is good).
Here's an example of a back routine I may use:
Pullups x 4-5 sets (or however many sets to 50 reps)
Bent-over Rows x 4 sets x 10-12, 8-10, 6-8, 4-6
Deadlifts (after warmup) 3 x 8, 5, 3 (or something like that)
Go as heavy as you can while hitting your target rep ranges with the best possible form. The key to good back development is full range of motion and strict form. You can cheat a little on the heavier sets, but keep it to a minimum. You won't build a quality back by using a lot of cheating.
As far as chest goes, it really depends on your build. I've been hitting my chest hard for years and it progresses very, very slowly. It's not my training methods, it's mostly my genetics. I've had to work hard to get what I have, but I'll never have one of those really full, massive chests. I'm okay with that because I know I can still craft a balanced, aesthetic physique. One thing that's helped me out is using dumbbells a lot. I rarely use barbells any more. With barbells you have the advantage of using more weight, but with dumbbells you can really work the range of motion to suit your build. Or in other words, it's not AS strict as using a barbell can be. The disadvantage: by having to control two separate weights, you won't be able to use as much weight. Find what suits you best, I suppose. In my opinion, chest is a tricky muscle group to train. If you don't have great genetics in that area, you really have to try hard and figure out what works best for your build. One exercise that's underrated in my opinion that I'll strongly recommend is DB Pullovers. Do them so that you're lying perpendicular to a bench and only the top of your back is touching the bench. Lower the dumbbell behind your head in a circular motion, dropping your ass to enhance the range of motion and stretch. Arnold said he thought that DB pullovers could help develop the rip cage, and since I've been using them for the past couple years, I can honestly attest to that. Even at the least, it's helped develop my serattus, which makes my midsection look better than it used to. Here's an example of a chest routine that I sometimes use:
Incline DB Press 4 x 10-12, 8-10, 6-8, 4-6
Incline or Flat DB Flyes 4 x 8-10, sometimes 6-8
DB Pullovers 3-4 x 12-15
Or to increase intensity, I may swap the flyes for another pressing movement.
Flex between your sets and do a LOT of stretching after your workouts. Really helps brings out fuller shapes of the muscles, in my opinion.
Peace
