ideal workout for cutting down fat (from my experience):
5 sets (easy)
1 minute normal plank
30 seconds left arm
30 seconds right arm
1 minute superman (cooldown)
lay down on your stomach with your arms and legs out so only your torso should be touching
keep your knees and elbows off the ground
*alternate between these leg lifts for 30 seconds each like 3 times, then finish off with a 1 minute leg lift*
do 3 sets of leg lifts which is where you lay flat on your back and hold your feet 6 inches in the air with your legs 100% straight
o_)_// < - that except lower
then do the same thing but lifting one leg up to about 75 degrees and the then back down
o_)_/_ your legs should never go under 6 inches from the ground and should always stay straight
last thing is stand up then jump and bring your knees as high as possible, do this 50 times
finish it off with running like a mile if you're out of shape and then increase that up to 5 miles
