so this is a very low effort video intent on showing a reasonably cheap way to get some form of core gains and lose the pudge from around the middle (if done thrice weekly)
the bells signify change of action
(i feel too ugly to do this in live action)
workout action lists:
Situps
Legups
V-ups
Russian Twists
Planking
variations help improve building but you can choose to simply stick with just doing:
Plank... Situps... russian twists
Legups and V-ups require more effort but result in more gains
