Context:

i have an exam in july and thus am pretty much homebound till then (corona is irrelevant for me) Decided to put the extra non-study time i have to some use. cleaned up my diet (500kcal deficient for 3 ish weeks now) and work out a bit as ive gained tonnes of weight in the past year of so (5'7 80kgs) the issue (limitation, really) being, i dont have a lot of money left on me, since my intership concluded, to join a gym.

But i do own some weights 2kgx2, 2.5kgx4, deadlift bar (7.5kgs~), a couple barbells and the thing you stand on to do calfraises and stuff. Its pretty evident that till exam results are in and i get a job (say mid Aug), i wont have money to join a gym

Course of action:

So instead of going for small reps + heavy weights, i decided to go for 100 reps (20x5) each exercise. by Aug, i wont really have any defination whatsoever and thus i decieded i should focus on setting up a habit of working out (foundation before the building. i do want defination dont get me wrong here but im in this for the long haul)

in order to delay any gratification and stay true to habit creation, im focusing on the areas that arent immidiately ivisible (legs, back, core) in order to get into a routine of working out im alternating between adding either new a exercise or adding more weight every 2 weeks and doing squats and romanian deadlifts and added calf raises along the way. ive been doing this 14 ish days now and ive added 2x2 to the deadlift bar, 2x2 to barbells for squats and body weight for calfrises (for now).

my weights should be able to last till Aug with this pace (i hope) while i add more excerises to increase the intensity.

Question:

is my approach sound? suggestions for excerises?
