Put it on scales on the ground? Then put the scales on a block and weigh it again?

It's not the maths way, but if it was really important to know I'd use luggage scales to see weight at different points.
But I'd just treat it like a machine. Ignore leverage, just put weight on til feel right. grunt. lift weight.

I like kettlebells a lot, definitely helps strength and functional muscle, and can build a lot of muscle.
Unlikely to gain massive muscle unless you’re chucking around 32kg+ kettlebells.
My non cycling or martial arts training is kettlebells, pull-up bar work and calisthenics type training and seems to be serving me well at the moment.

Good ChatGPT fodder …
The weight you're lifting in a landmine exercise changes with the angle due to the principles of physics, specifically the lever arm and torque. To estimate the effective weight as the angle changes, you can use the cosine of the angle between the bar and the ground.
Here's a simplified way to calculate it:
Determine the Total Weight of the Bar: Add the weight of the bar (half of it, since one end is fixed) and the weight of the plate. If the bar is 20 kg and the plate is 20 kg, then the total weight is 10 kg (half of the bar's weight) + 20 kg (plate) = 30 kg.
Calculate the Effective Weight at Different Angles: The effective weight you're lifting is equal to the total weight multiplied by the cosine of the angle between the bar and the ground.
[ \text{Effective Weight} = \text{Total Weight} \times \cos(\text{Angle}) ]
- When the bar is horizontal (0 degrees), (\cos(0) = 1), so you're lifting the full 30 kg.
- As the angle increases, the cosine value decreases, reducing the effective weight you're lifting.
- When the bar is horizontal (0 degrees), (\cos(0) = 1), so you're lifting the full 30 kg.
Examples at Different Angles:
- At 45 degrees, (\cos(45) \approx 0.707). So, the effective weight is ( 30 \times 0.707 \approx 21.21 ) kg.
- At 60 degrees, (\cos(60) = 0.5). The effective weight is ( 30 \times 0.5 = 15 ) kg.
- At 45 degrees, (\cos(45) \approx 0.707). So, the effective weight is ( 30 \times 0.707 \approx 21.21 ) kg.
This method gives you a rough estimation. In practice, other factors like the distribution of weight along the bar, the specific mechanics of the landmine device, and your position relative to the bar can affect the actual weight you're lifting.

Seeing as I had it fired up already to write a bunch of equations in Latex format for me:
Torque due to Uniform Mass:
(1)Torque due to Point Mass at p:
(2)
The total torque:
(3)
The force equation:
(4)
Expressing forces in terms of the angle (θ):
(5)
Solving for F [edit - corrected]
m is the uniform mass of the lever.
n is the point mass added at distance p from the pivot.
l is the length of the lever.
g is the gravitational acceleration.For an IWF Men's Olympic bar, with a 20kg plate, at 45° & 60° (on earth...)

Yup, thats what i thought.

Divide by 9.8 - so approx 36kg and 42kg
Which is bollocks.
So chatgpt got it wrong.

I have just ordered a pair of these to try: https://startfitness.co.uk/products/adidas-the-total-weightlifting-shoes-white?variant=43442456690896
I would go shoeless but my gym floor is really cold... so I end up with blocks of ice for feet.

I’m spoiled; I have a landmine attachment on my squat rack in my bedroom. But no scales 🤣

This is just reminding me I 100% need to start using the landmine again. It's so much fun and so productive and I have no idea why I stopped.

Late to the party but a goals post:
Pinky and the Brain time cos these have been my goals every year since the start of 2020.- Bench 140
- Squat 200+ (I've hit 160*10 and 180*5 so I reckon it has to be a mental barrier at this point).
- Deadlift infinity.
Current bonus goal is to not lose any more weight for a bit. It's been unintentionally trending downwards the last six months to the point where I know I can't afford to lose any more and still make progress. I also don't really want to get fluffy for the sake of inflating my numbers so it's a careful balance and I just need to actively get on top of it.
- Bench 140
Learn the basic moves of swing, goblet squat, maybe snatch if you want then you can do something like:
3 rounds of (40 seconds working, 20s rest)
Swing
Jumping jacks
Goblet Squat
Burpees
Minute between each round.
