Caroline Girvan: what weights do I need to add?

[Stumpedasatree]

Just starting out with her workouts, I am run-fit but not terribly strong. I have a 12kg kettlebell and a 6kg kettlebell and 6kg dumbells. What else is best to add?

I do the kettlebell swings with the 12kg currently but overhead stuff with the 6kg one.

I currently have 5k dumbbells and need to increase so am about to order some 7.5kg ones. I use a 10kg Kettlebell.
Caroline G often uses 2 x 15kg which is way too heavy for me, I could possibly use them for lower body but no way for upper. (I also love Juice and Toya on YT, they're great!)

Thanks @Gherkingreen I've not heard of those will have a look!

@Stumpedasatree I realise I did that annoying thing where I didn't answer your question!
I reckon start with the weights you have, then when the workouts become less challenging, up the weight. Or, up the reps with the weights you have.
Form is super important to avoid injuries and get the best results. I've just done a workout this morning with a new (to me) YouTube trainer called Penny, Garage Girl Fitness on IG/YT, really enjoyed it.
I'm late 40s and love doing weights at home, definitely feeling stronger and more toned. I also walk at least 8/10k every day with my dog and do HIIT type workouts a couple of times a week.

I use 5 kg dumbbells for most of her workouts, and have been using them for the past 3 years. But I always increase the speed and number of repetitions. I also have a 12 kg set that I use if I want to challenge myself. I know I need an intermediate set but never seem to get around to buying it. I'm not too bothered though as I'm happy with my muscles as they are, so I'm not looking to achieve hypertrophy. I also do a lot of push-ups to increase strength, and planks and other abs work for core strength and stability.
