Amazon isn't a as good as it used to be but you can still find some great deals on pretty good bells. I bought a pair of 20kg bells that I'm happy with last year for like a hundred bucks. I think they're Yes4All or something like that. The rogue and kettlebell kings bells are nice but I don't think it's necessary to spend that much

Looks like you may just need more time/work put in with the heavier bell sizes. I think a lot of people get excited when they move up to a heavier bell that they try to keep that momentum going and try to move up to quickly. Spending more time putting in work at a new heavier bell helps to "own" that weight like Grant says. For example if you moved recently from say 36kg to 40kg you may either just need to spend more time building up the 40kg. If you can't hit say 5 getups with the 40 but you can do 3 or maybe 4 then stick the 3 for a couple weeks and work on adding an additional getup over time. Or you could spend more time working the 36kg doing 5 per arm OTM for a few weeks to really own that weight until it feels easy. Then start reducing rest time. Work on getting 5x36kg unbroken or 1 every 30 sec kind of thing. Hopefully that makes sense lol.

@Joe Zaga now worries dude. Going back to the 32 and rebuilding back to the 40 is a solid plan. It will help you improve technique and gain the strength to really own the 32 until that feels way too easy. If you do your 10 getups with the 32 for a few weeks and get to a point where it felt so easy that you could do it again then I'd say you've built the required strength to move back into the 40kg range. Your body will give you all kinds of signals so you just have to learn to read the signal and adjust accordingly. So if you make the 32 your bitch and start getting fired up and excited for the 40 that's a sign that you're ready. Last time it sounds like you got squirrely when life got hard. I do that. Its normal. When it happens you just have to ask yourself do I really need to change things or am I just overwhelmed. Most times you just need to trust the process and stay the course. If life gets hard, your push back harder. That's when change really tales place. You got this bro

Suitcase deadlifts are very underrated for strength endurance and hypertrophy. Unilateral and doubles. With doubles it great for overall lower body anterior and posterior similar to how the leg press works and is fuckin great for my back

I like how strong doubles feel but I should probably do more of the unilaterals too lol

Hey Karl, welcome. You will get plenty of encouragement here. This community is great for that. Make sure to check out the classroom section. The videos unlock as you watch them in sequence. Good luck.

Keep in mind that with kb training the progression is typically slower than barbell/dumbbell. With kbs there are continued adaptations that occur within the body that go almost unnoticed because you dont get a visual feedback like body composition. Processes that involve the body's energy systems, recovery (set/rep recovery and session recovery), and cardio vascular adaptations. So while you may have just increased bell sizes for a particular movement and are beginning to pull them into your 70% there are several internal processes happening concurrently. These take longer to occur so staying at a particular increased bell size for a few weeks allows for greater adaption to really own that new bell size. Hope this helps.

Well when pulling heavier bells into your 70-80% (moderate bell) range you would use the bell you moved up to and adjust the sets, reps, intraset (rests in between exercise sets) rest periods, and intrworkout (rests between exercises) rest periods, total session time, etc. Remember the main progressive overload (drivers of hypertrophy) units that you can adjust to ensure PO is occurring is by increasing over time is the sets, reps, or weight of a given exercise. Typically a trainee would choose 1 to 2 unit to adjust at a time. So in this case you would be looking to increase volume either by sets or reps or both (both is exponential). Or you could increase session intensity by reducing rest periods. You could also increase session density by doing more overall session volume in less time. Plenty to choose from.
