no wonder people get put off training, this sort of thing is made so complicated its ridiculous!
eat a healthy balanced diet
drink the right amount of water according to what you are doing
just train....use the stuff around you, hit pads, kick pads, bagwork, clinch, good old fashioned exercises that you dont need any equipment for
squats, jumping squats, squat thrusts
lunges, walking lunges, jumping lunges
burpees, burpees with a press-up, burpees with a tuck jump
sit-ups, crunchies, side-bends
wide arm press-ups, narrow arm press-ups, press-ups with a clap
plank, side plank
if theres a road...go running, if there is countryside go running
if theres a hill do hill sprints, if there are steps run them
use another heavier person to hold a belt around u and pull you back as u run/punch/knee/kick
it does not need to be such complicated shit, u dont need loads of different equipment you just need your environment and some imagination!
