For the last month or so, I've been doing a 15 minute full body kettlebell workout about 5 times a week with an 8kg kettlebell. I find the 15 minute slot brilliant as it's easy to fit into the day and there's no excuses to avoid it as it's over so quickly. I'm finding the 8kg fairly easy, or at least maybe not enough of a challenge. I wondered if anyone could advise whether it would be ok to simply start doing the same routine with a 10kg kettlebell, or whether it would be more beneficial to use the 8kg for a longer (30 minute?) routine? I know 15 mins isn't much, but along with a sensible diet, I've gone from steadily losing 1lb a week to losing 2lbs a week just by adding in this regular 15 minute session, and i do feel a lot leaner, so it is definitely paying off one way or another.
I'm not looking for miracles - just keen to know what would be the best next step for me.
In terms of my objective - i see the healthy eating as the route to weightloss and the kettlebells as a way to tone up as I lose (in addition to some yoga and running along the way). I am aware that a 15 minute routine alone isn't going to make me lose weight in the long run, so I'm not asking "what's the best way to lose weight?" - I'm wondering what the best next step would be for continuing to strengthen and tone as I lose.
Thanks in advance for any advice.
