Thats expensive. I am start easy but I will upgarde when the dumbells outlive my capabilityYou can get Powerblocks now for regular price. $700ish shipped up to 90lbs per hand.
Anyway, I started with barely 10 push up (one go) & barely 20 sit up less than a month ago to be able to do 40 push up & 70 sit up (one go) today.
The weather is still too cold, maybe 40ish F & rainy, so I did not go out for run. But I discovered I can get of intensity out of stationery run with knee rise to touch the hands (High knee run?). 1 min & I am totaled at my level now.

The dumbell has still not a delivery date (last checked on Amazon), hope they come soon.
One thing about working out, is, you feel good after it.
