Haven't run for years but keep in shape using kettlebells and dumbbells most days. You can get a very good workout using light to moderate weights if you know what you're doing.

A kettlebell is superb for helping core strength, cross body stabilisation and working your hip flexors. Very underrated piece of equipment is the kettlebell.

I've also got a pair of max' parallettes and a weighted vest for dips, inverted rows and pullups etc. Bodyweight exercises are excellent. Bulgarian split squats are your friend with or without weights.

Can thoroughly recommend rowing machines too. Found training using HIIT protocols was better for me than just rowing continually. I've gone through several and would love to buy another one. I always go for fold aways as we're pushed for space given the equipment I've got.

You've no need to run for cardio although the benefits of short powerful sprints shouldn't be overlooked. I've never really understood the fascination of steady state cardio as it only really makes you good at steady state cardio.
