@hellokitty Right, here we go...
Brief video analysis:
Day 1
Ex 1. Too much weight
for now. Poor form.
Pull back the weight 15lbs, and focus on your form. You lean back, you have the DBs pressed in front of you in the top starting position. Immediate pointer is that your
eccentric is far too fast. Your average eccentric is 1 - 1.5 seconds long. It's not enough, it's not effective - all you are doing is letting your arms drop and almost bounce out of the bottom of the press. I would advise a 3 second eccentric. This links in with the next pointer.
CONTROL. With such a fast eccentric, you have little control of the movement and your target muscle group.
SLOW DOWN, feel each portion of the range of motion, feel your chest engage and maintain tension to control the load to the bottom of the movement. But this is only optimal if you (pointer 3)
refine the correct movement pattern. I need you to use your imagination on this. Just before you commence the eccentric portion of the movement, notice how your forearms are vertical like a flag pole? You need to maintain this vertical forearm position as you descend. Watch your video, you see that your wrists collapse inwards, creating passive elbow flexion. So rather than your forearms remaining vertical like that flagpole, they angle inwards like the Leaning Tower of Pisa. This is putting the load (weight) through your tricep, not your chest. Why? Because it is passive elbow flexion. In order to reverse elbow flexion, you go through elbow extension. Guess what that uses? Your tricep. Do you want to put disproportionately more load through your tricep with this movement? No, obviously not, because you're trying to work your chest. So to reiterate, vertical forearms through the full range of motion of the movement put the load onto the chest, as the pecs are the prime movers for the purpose of horizontal adduction. Just one final analogy to really reiterate this. Put your right hand on your right shoulder. Your left hand on your left shoulder. Lift your elbows up to the same height as your chest. Squeeze your elbows together in front of your chest. Keep them at this height, and slowly move your elbows outwards, as if you are Christ the Redeemer but touching your shoulders. Then squeeze your elbows back together in front of your chest. This is the movement you are doing with virtually every chest press, whether it is Barbell Bench, Dumbell Bench, or Flyes. This is where peak force goes through your chest. If you can grasp this, you will understand why you want to keep your triceps out of the chest movement.
To summarise - drop the weight, slow the fuck down to a 3 second eccentric, and refine/relearn the movement patterns.
Ex 2. Too much weight, slow the fuck down, AGAIN,
CONTROL. THE. MOVEMENT.
Not much else to add.
Put the ego aside, drop the weight. Stop letting the weight stack hit and clunk the other weights. With flyes, I want to see a 3 second eccentric with a 1 second squeeze the the peak of horizontal adduction. I don't want to hear shit coming from that weight stack. Like Exercise 1, your eccentric is too fast, around 1-1.5 seconds. You've no control, by rep 7 you begin to compensate by rounding your upper spine, encouraging internal rotation of your shoulders. How can I tell? Your elbow is disengaging from the elbow pad, and you being to press through your wrists. You're asking for injury. Lower the weight, slow the movement,
FEEL THE STRETCH at the bottom,
FEEL THE SQUEEZE AND MUSCLE RECRUITMENT at the top. Keep your chest "proud", don't round your back or your shoulders. The reason you made this adjustment, subconsciously, is because you are trying to leverage other muscles to create the desired output, even though they shouldn't be involve din such a movement. Remember the analogy I gave earlier about hands on shoudlers and squeezing elbows together. Same applies here. You must try to move your distal humerus (elbow) towards the midpoint of your chest. Nothing more, nothing less. Your wrists shouldn't be in this equation, and you shouldn't be rounding. You've gone to failure, but were there really any effective reps? Not really. Lower the weight, proud chest, feel the stretch, feel the squeeze, nice and slow, and then go to failure. You'll be surprised how little weight you needed.
Ex 3. Too much weight. Too fast. No control. Poor base.
Spotting a trend with from the last two exercises? Your eccentric is too fast, probably because the weight is too heavy. Therefore you have no control. You have no mind muscle connection, you are not allowing adequate time for the muscle to stretch and experience tension under a load. No mechanical tension of your musculature = no stimulus = no growth. DROP THE EGO. REDUCE THE WEIGHT. SLOW THE ECCENTRIC - 3 SECONDS! STOP LETTING THE WEIGHT CRASH DOWN, CLUNKING THE STACK AND ACTUALLY CONTROL IT.
Now you'll notice I've added another pointer. Poor base. Your feet are all over the place. Your lower chain is therefore "loose". Establish strong footing, use your quadriceps to push your hips into the backrest, brace your core,
and then press. If you break the chain, you lose your core stability, and then you loose strength. You loose strength and then you do what you did, which was almost stand up in order to attempt to leverage... something. Kudos for not rounding your shoulder, and maintaining more a proud chest in this movement. But still needs a lot of improvement.
Ex 4. Too much weight. Too fast. Not enough control.
This one is different, as it's horizontal
abduction. Same kind of principles apply, in the sense that it is all about what your elbows do. With pulling motions, you need to imagine your arms are hooks. You lead the movement with your elbow, as if you're thrusting backwards. Your biceps are merely an accessory to the prime mover(s), which in this movement would be multiple muscles in your upper posterior chain. I think your movement pattern is decent in this, BUT guess what... Too heavy. Too fast an eccentric. Still not enough control, but an ever so slight improvement on the previous 3 exercises. With machine pull exercises, you should do a 3 second eccentric and a 1 second hold. With free weight exercises, only a 3 second eccentric unless the movement feels safe to implement a hold.
Ex 5. Poor base. Absolute limit on weight until form is standardised.
This is better. The movement pattern is decent, the intensity is good. Your base isn't rigid enough. You need to lean forward a slight bit more, lock your feet in at shoulder width, and brace your core. Stop jumping. I can't tell if you do that because you're using too much weight or that your lack of core stability is causing you to do it to build the momentum for the movement, but I'll give BoD that it's just the poor base - do not increase weight until you've nailed this, it's a nasty exercise if it goes wrong. Also recommend cable lateral raises to complement DBs.
Ex 5. Too fast, no control.
As far as exercises go, you can't fuck this one up. But you can be inefficient. Slow. Down. Feel the stretch in the lengthened position, feel the squeeze and burn in the shortened position. Control every second of the movement, 3 SECOND ECCENTRIC AND 1 SECOND HOLD.
