slow on the way down, explode on the way up. full extension. start light, work your way up slowly. simple

TL;DW Both are good. Not exercising is bad for muscle growth.

As someone with some previous shoulder issues, I'd say the most important part of going slowly & controlled on the negative portion is reduced risk of injury. Keeping your muscles doing the work as you come down means less pressure on your joints, vs. just letting gravity take over & having your body weight slam down on them.

Typically bodybuilders will recommend doing a slower, controlled eccentric movement, mixed with an explosive upwards movement. This allows you to control the rep and get your twitch muscles activated. That being said, if your stabilizer muscles arent up to the challenge, and youre shaking like a leaf, then the weight is too heavy. Stay safe! 👍

My reps are so fast, that I count them like 1, 2, 5, 10, 20, done.

[bizzarejelly]

I like slow reps because it always feels like I'm hitting the muscle I'm trying to hit when I hit my reps quickly sometimes I feel like the momentum spreads the movement to other muscle groups instead of the one I'm trying to focus on but yeah always go heavy and till you can't squeeze out another rep

[JaxBlade]

I always look forward to these videos. They're fun informative and you can tell the work that went into them :)

[MikeCola]

For hypertrophy and safety...I like a slow eccentric speed. By lowering the weight slowly, you are in more control (can keep continuous tension on the muscle) and can decelerate the weight safely at the transformation point to change direction.

[mathewkelley]

I have been doing both on a 10 set workout. 1st heavy, 2nd light, 3rd heavy, so on. I've noticed a huge difference in muscle gain and size.

[sc-sportscompilations]

I don't think that all of the viewers will even understand what was said in the video so let me explain :
Don't lower the weight, keep the weight as it is as long as you have good form and mind muscle connection. Now what you need to do is to lift regularly at the positive portion of the movement, BUT make sure you keep the negative portion of the movement SLOW AND CONTROLLED because you are simply stronger in the negative portion of the movement than you are at the positive portion of the movement. This will insure more muscle growth.

[PerryBattles]

Slow negative, fast positive, good squeeze at the top :).

[lucianox]

slow in The negative, fast in The positive💪💪

[LONNiETOWN]

Lifting light weight slowly has really helped me grow muscle lately! I only do it for shoulder and bicep and tricep though!

[jakemcphee]

TUT (Time Under Tension) is very important imrpoves strength and muscle hypertrophy which is what you want. You don’t need to go slow on the way down and explode on the way up but instead stay at the same tempo and slow when training for bodybuilding and hypertrophy.

[allanjoarder]

if faster reps = more weight.. there is a higher probability that you are cheating your movements / exercises and therefore leads to injury.

[mhtjabermht]

will American use kg instead of pound anytime soon?

[damianblue]

hey picturefit you talk alot about fitness...but the question is....do you even lift brah?

[AlejandroGarciaIglesias]

This is interesting. I don't know if it makes sense, but I concluded on doing fast reps to engage fast-twitch fibers, and then as the muscle gets fatigued reps slow down automatically engaging slow-twitch fibers and finally fatiguing all of the fiber types. Also, I've read "Fast-twitch fibers can also recruit slow-twitch fibers: endurance training at high-intensity intervals can be effective in improving aerobic power".

[Drunken_Hamster]

Fast up, slow down.

Dilemma solved. Maximum efficiency attained.
